Our heartbeat serves as a vital indicator, which shows how well our heart functions. The heart experiences irregular rhythms ...

When your electrical system is working normally, the two upper chambers of the heart (atria) contract and pump blood into the two lower chambers (ventricles) in a well-coordinated way. This results in ...

Atrial flutter and atrial fibrillation (AFib) are heart rhythm conditions that occur when the upper chambers of the heart (known as the atria) beat too quickly. Atrial flutter involves the atria ...

This case highlights the diagnostic value of Holter ECG monitoring in uncovering spontaneous arrhythmia mechanisms. Several ...
