A heart block is an electrical problem where signals from your heart’s upper chambers (atria) don’t properly reach the lower chambers (ventricles). This disrupts your heart’s normal rhythm and can…

PAC stands for premature atrial contraction, while PVC means premature ventricular contraction – both are extra heartbeats that occur earlier than normal but originate from different heart chambers. PACs come…

A PVC is a premature ventricular contraction – an extra heartbeat that starts in your heart’s lower chambers and happens earlier than your normal heartbeat. Most PVCs are harmless and…

Normal sinus rhythm means your heart beats in a regular, healthy pattern controlled by the sinoatrial (SA) node, typically between 60-100 beats per minute. On an ECG, normal sinus rhythm…

Tachycardia is a condition where your heart beats faster than 100 beats per minute while at rest. This rapid heart rate can cause symptoms like chest pain, dizziness, shortness of…

Bradycardia is when your heart beats slower than 60 beats per minute at rest. This condition can be normal for athletes or cause symptoms like dizziness and fatigue in others….

Atrial fibrillation (AFib) is an irregular heart rhythm where your heart’s upper chambers beat chaotically instead of in sync with the lower chambers. This common heart condition affects over 6…

An arrhythmia is an irregular heartbeat that occurs when your heart beats too fast, too slow, or with an uneven rhythm. Your heart’s electrical system controls this rhythm, and when…

Cardiac event recorders are portable ECG devices that continuously monitor your heart rhythm for weeks or months, capturing irregular heartbeats that standard tests often miss. These specialized monitors help doctors…

Portable ECG for home use means FDA-cleared devices that you can operate yourself to record heart rhythm without medical supervision. These consumer-grade monitors capture basic ECG data but aren’t substitutes…
