What is an Arrhythmia?

You are likely reading this article because you are interested in learning more about the causes of arrhythmias. An arrhythmia, or irregular heartbeat, is a condition that alters the rate or cadence of one’s heartbeat. Your heart may beat at an irregular rhythm, either too rapidly or too slowly. Medications or procedures are implemented to regulate the irregular rhythms of arrhythmias.

In order to diagnose a heart arrhythmia, the Best Cardiologist in Singapore will typically perform a physical examination and consult with you about your medical history and symptoms. Tests may be performed to corroborate an irregular heart beat and to identify potential causes of arrhythmias, such as thyroid disease or heart disease, in the vast majority of cases.

Holter monitors, echocardiograms, implantable loop recorders, event recorders, and electrocardiograms are among the most frequently administered tests for the diagnosis of arrhythmia. The electrical activity of the heart is detected by attaching sensors to the thorax and, on occasion, the limbs or legs, in order to perform an electrocardiogram (ECG). Ensure that the electrocardiogram (ECG) accurately records the timing and duration of each electrical phase of the heartbeat.

In contrast, a Holter monitor is a portable ECG device that can be worn for a day or longer to record your heart’s activity as you engage in your daily routine. The peripheral ECG is employed exclusively to identify sporadic arrhythmias when used in conjunction with an event recorder. The sole requirement is to press a button when symptoms appear.

The best cardiologist in Singapore may attempt to induce an arrhythmia after performing the aforementioned tests by enlisting the help of other individuals. Your doctor may decide to perform a stress test if a specific arrhythmia is exacerbated or inducible by activity. During a stress test, the heart’s activity is monitored as you pedal a stationary bicycle or meander on a treadmill.

The best cardiologist in Singapore may also recommend a till table test if you have experienced fainting spells. Your heart rate and blood pressure are monitored as you lie supine on a table. As a result, the table adopts an upward incline, which gives the impression that one is standing. The doctor will monitor the response of your heart and the nervous system that regulates it to the change in angle.

The final stage is electrophysiological monitoring and mapping. By passing thin, flexible tubes with electrodes through the blood vessels to various locations in the heart, a doctor conducts this test, which is also known as an EP study. Once the electrodes are in position, the distribution of electrical impulses throughout the heart can be monitored.
