Should I be worried about Sinus Arrhythmia?

Respiratory sinus arrhythmia is not considered a major health concern. However, other arrhythmias can sometimes indicate heart disease. An older person with a severe arrhythmia may require a pacemaker.

Is Sinus Arrhythmia a heart condition?

This condition is benign. It’s a naturally occurring heartbeat variation, and it doesn’t mean you have a serious heart condition. In fact, this condition is common in young, healthy adults and children.

What causes short PR interval in ECG?

Short PR Interval. A short PR interval (<0.12 sec) may be caused by a pre-excitation syndrome (Wolff-Parkinson-White), ectopic atrial pacemaker or AV junctional rhythm. Wolff-Parkinson-White with short PR interval (0.08 sec) and delta wave (red arrows).

What does sinus rhythm – borderline short PR interval mean?

A short PR interval is the decreased distance between two of the waves on a Read More what does sinus rhythm – borderline short pr interval mean on an ecg? Usually nothing.: The pr interval, the time between the P wave (atria contract) and the qrs (ventricles contract) is typically between 0.12 and 0.20 seconds.

What does abnormal P waves with narrow QRS complex mean?

In ectopic atrial pacemaker or AV junctional rhythm may be seen a short PR interval with an abnormal P waves with narrow QRS complex. Related articles: EKG waves, abnormal waves and intervals. The P wave represents atrial depolarisation, it is the result of overlaying the electrical activity of both atria.

What is not included in the PR interval of the heart?

It does not include the duration of conduction from the Sinus Node to the right atrium (Sinoatrial conduction). The PR interval also includes the atrial repolarization (atrial T wave), which is directed opposite to the P wave axis, but atrial repolarization usually has low amplitude and the PR segment is frequently isoelectric 1.
