The heart has its own electrical system, and electrical impulses are essential for the heart to beat and pump blood to the entire body. Sometimes, the heart's electrical system may not work properly due to heart disease, certain medications, or unknown reasons. Changes in the heart's electrical system can cause abnormal heart rhythms, also known as arrhythmias, which can make you feel like your heart is racing, thumping, fluttering, pounding, or skipping beats. This sensation is called heart palpitations and can be triggered by stress, anxiety, panic, fear, caffeine, alcohol, spicy food, or pregnancy. While palpitations are usually not serious, it is important to consult a doctor if they occur frequently or are accompanied by other symptoms such as chest pain or discomfort.

Heart palpitations
The heart has its own electrical system, and electrical impulses are essential for the heart to beat and pump blood to the body. Sometimes, the heart's electrical system may not work properly due to heart disease, certain medications, or unknown reasons. Changes in the heart's electrical system can lead to abnormal heart rhythms, also known as arrhythmias. Atrial fibrillation (AFib or AF) is a type of arrhythmia characterised by a disrupted, fast, and irregular heartbeat. Other types of arrhythmias include paroxysmal arrhythmias, which start and stop suddenly, and tachycardia, which involves problems with the heart's upper or lower chambers.
If you experience heart palpitations, it is important to consult a doctor, especially if they are frequent or persistent. Your doctor will ask about your medical history and may recommend tests such as an electrocardiogram (ECG or EKG), a Holter monitor, an echocardiogram, blood tests, or a stress test. Treatment options depend on the underlying cause of the palpitations and can range from medication to procedures, surgery, or devices to correct the problem. In some cases, lifestyle changes, such as managing stress, following a heart-healthy diet, and staying active, can help control palpitations.
While heart palpitations can be unsettling, they are a common occurrence and usually not serious. However, it is always advisable to seek medical advice to ensure proper diagnosis and treatment if needed.

Atrial fibrillation
The human heart has its own electrical system, which is essential for it to beat and pump blood to the body. Atrial fibrillation (AFib or AF) is a type of arrhythmia, or abnormal heart rhythm, where the heart beats irregularly and fast. It is the most common serious abnormal heart rhythm, affecting more than 33 million people worldwide as of 2020. The percentage of people with AF increases with age, with 0.1% under 50 years old, 4% between 60 and 70 years old, and 14% over 80 years old being affected.
AFib can lead to blood clots, stroke, heart failure, and other heart-related complications. The risk factors for AFib include high blood pressure, valvular heart disease, heart failure, coronary artery disease, cardiomyopathy, congenital heart disease, lung-related issues such as COPD, obesity, sleep apnea, excess alcohol intake, tobacco smoking, diabetes, and emotional stress. It is often diagnosed by feeling the pulse and interpreting an electrocardiogram (ECG), which measures the heart's electrical activity.
AFib is a progressive disease with four stages. In the first stage, an individual has not been diagnosed with AFib but may have abnormal structural or electrical problems in their heart that can lead to it. Treatment can begin early to slow or stop the progression. Once diagnosed, treatment options include medications to control the heart's rhythm or rate, surgery, or managing other health conditions. Healthy lifestyle changes, such as weight loss, increased physical activity, and reducing alcohol intake, can also help lower the risk and reduce the burden of AFib.
If you are experiencing symptoms of AFib, it is important to consult a healthcare professional for proper diagnosis and treatment.

Heart arrhythmias
The heart has its own electrical system, and electrical impulses are essential for the heart to beat and pump blood to the entire body. A healthy heart contracts and relaxes in a steady rhythm of 60 to 100 beats per minute. However, sometimes the heart's electrical system may not work properly due to heart disease, certain medications, or unknown reasons. This disruption in the electrical system can cause abnormal heart rhythms, also known as arrhythmias.
Arrhythmias are characterised by irregular and fast heartbeats. There are two main types of tachycardia or arrhythmias: supraventricular tachycardia, which is a problem with the upper chambers of the heart, and ventricular tachycardia, which affects the lower chambers. Atrial fibrillation, or AFib, is a common type of arrhythmia where the heart beats abnormally fast. It is characterised by a disrupted heartbeat and can cause a fluttering feeling in the chest.
If you suspect you have AFib or are experiencing symptoms such as heart palpitations, it is important to contact your doctor. They may recommend tests such as an electrocardiogram (ECG or EKG) to measure your heart's electrical activity and detect any rhythm problems. Holter monitors can also be worn continuously for a day or two to record your heart's activity during normal activities. Other tests may include blood tests, urine tests, stress tests, echocardiograms, and cardiac catheterization.
Treatment options for arrhythmias depend on the underlying cause and can include medications, procedures, surgery, or devices such as pacemakers. In some cases, cardioversion may be used, which involves a mild electric shock to reset the heart's rhythm. Ablation is another procedure where parts of the heart contributing to abnormal beats are burned or frozen, creating scar tissue that blocks abnormal electrical signals.
It is important to note that occasional heart palpitations during periods of emotional or physical stress are normal and usually nothing to worry about. However, frequent or consistent palpitations may indicate a serious abnormal heart rhythm, and it is recommended to consult a doctor in such cases.

Emotional triggers
Heart palpitations, or the feeling of being aware of your heart beating, can be triggered by emotional or physical stress. These triggers can cause the heart to beat too fast, too slowly, or irregularly. Emotional triggers can include feelings of anxiety, stress, fear, panic, and even happiness or excitement.
Anxiety is a common emotional trigger of heart palpitations. It is normal to experience a range of emotions, such as fear, uncertainty, anxiety, and low mood when dealing with heart palpitations. Heart palpitations can also be part of your body's reaction to feelings of anxiety or panic. Calming activities like yoga, meditation, or mindfulness can help control heart palpitations triggered by anxiety.
Stress is another significant emotional trigger for heart palpitations. Managing stress through healthy lifestyle changes, such as regular exercise, a heart-healthy diet, quitting smoking, reducing alcohol intake, and staying active, can help keep heart palpitations under control.
Other emotional triggers may include feelings of fear and panic. It is important to note that occasional palpitations during emotional stress are normal and usually nothing to worry about. However, if you experience frequent or consistent palpitations, it is essential to consult a doctor as it may be associated with a serious abnormal heart rhythm or another heart condition.
In summary, emotional triggers such as anxiety, stress, fear, and panic can lead to heart palpitations. While occasional palpitations due to emotional triggers are typical, frequent or persistent palpitations may indicate an underlying heart condition. It is always advisable to seek medical advice if you have concerns or experience any unusual symptoms.

Electrocardiogram (ECG/EKG)
The heart has its own electrical system, with electrical impulses essential for the heart to beat and pump blood around the body. The heart has four chambers, two on the left and two on the right, and in a healthy heart, regular electrical signals cause these chambers to contract and relax in a steady rhythm of 60 to 100 beats per minute.
An electrocardiogram (ECG or EKG) is a test used to evaluate the heart's electrical activity. It is a quick, simple, and non-invasive procedure that can be performed on an outpatient basis or as part of a hospital stay. Electrodes (small, sticky plastic patches) are placed on the skin at certain points on the chest, arms, and legs. These electrodes are connected to an ECG machine by lead wires, and the electrical activity of the heart is measured, interpreted, and printed out. The procedure is painless, although some people may experience discomfort when the electrodes are removed, and skin irritation can occur if the patches are left on for too long.
An ECG is often used as a baseline for future comparison, and it is an integral part of the initial evaluation of a patient suspected of having a cardiac-related problem. It is also used to check for abnormal heart rhythms in people experiencing heart palpitations. Heart palpitations are a common and usually non-serious symptom, but they can sometimes indicate an underlying heart condition.
The evolution of the ECG from a string galvanometer to a modern computerized machine has made it the gold standard for diagnosing various cardiac diseases.
