The diagnosis is sinus rhythm with interpolated premature ventricular complexes, in a trigeminal pattern, with retrograde concealed conduction. The rhythm is irregular, but there is a repeating ...

The rhythm is either sinus rhythm or not sinus rhythm. Sinus rhythm refers to the origination of the electrical activity coming from the sinus node — also known as the sinoatrial node, or SA node.

There are only a few sinus rhythm QRS complexes available to examine on this ECG. Using lead V1 an incomplete right bundle branch block is seen. A prolonged QT interval is present that extends all the ...

In tracing "a" of Figure 1, there seems to be only one P wave in front of each QRS complex, suggesting sinus rhythm. However, during the compensatory pauses after the PVCs (↑) in tracing "b," there ...

What Is a Normal Sinus Rhythm? Normal sinus rhythm is when your heart beats in a regular, organized way. Your body has a built-in pacemaker called the sinoatrial (SA) node, or sinus node. It uses ...

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 ...

Dr. Kathleen Maginot answers the question: 'Abnormal Heart Rhythms in Children?' — -- Question: What types of abnormal heart rhythms are more common in children? Answer :There are many ...

The EAST—AFNET 4 (Early Treatment of Atrial Fibrillation for Stroke Prevention) trial investigated whether rhythm control therapy—with antiarrhythmic drugs or atrial fibrillation ablation—delivered ...

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 ...
