Sinus rhythm is the term for the regular pattern of heartbeats driven by the heart’s natural pacemaker, the sinus node. Variations like sinus tachycardia (fast heart rate) and sinus bradycardia (slow ...

The diagnosis is normal sinus rhythm, interpolated premature ventricular complexes (PVCs) in a trigeminal pattern, retrograde concealed conduction, intraventricular conduction delay, and old inferior ...

Premature ventricular contraction (PVC) is a type of abnormal heartbeat, or arrhythmia. It happens when the heartbeat begins in the lower, rather than the upper, heart chambers. This creates an ...

Have you ever heard the term 'sinus arrhythmia' and wondered what it means? You might have come across it during a routine check-up or on an Electrocardiogram (ECG) and felt concerned. The word ...

Tachycardia describes when the heart beats faster than normal. Sinus rhythm with tachycardia occurs when the sinus node fires electrical impulses abnormally quickly. Inappropriate sinus tachycardia ...

Sinus tachycardia is the most common and often neglected rhythm disturbance encountered in clinical practice. Whether appropriate or not, it is often associated with troublesome symptoms, and ...

This ECG is challenging. The rhythm starts as normal sinus rhythm with a right bundle branch block, then a wide-complex tachycardia develops in a left bundle branch block pattern. The important thing ...
