1. Normal sinus rhythm 2. Non-conducted premature atrial contractions (blocked PACs) If a premature atrial contraction occurs when the AV node has not yer recovered from the refractory period, the ...

Atrial Tachycardia occurs when a area not within the sinus node, but still confined to the atria creates action potentials at a rate faster than the sinus node AND at a rate > 100 beats per minute.

The last of three articles on using an electrocardiogram to assess the heart’s electrical activity focuses on causes of cardiac rhythm and conduction abnormalities and how to spot them This is the ...

A specialist tells how to interpret subtle changes on the ECG, ... or stenosis, ectopic beats, enlargement of the heart, enlargement ... than anticipated could indicate left-atrial ...

ECG plays an important role in detection of several stroke risk predictors including atrial ... higher automaticity – ectopic beats; and re-entry – atrial tachyarrhythmia; and higher ...

The ECG abnormalities included atrial ectopic beats, ventricular premature beats (VPBs), bradycardia, and ventricular tachycardia (VT), as well as T-wave abnormalities and prolonged QT intervals.

When ventricular ectopic beats account for 10-20% of total QRS complexes on a 24-hour tape, the patient is at risk of developing a left ventricular dysfunction. 7,8 If your patient has ventricular ...

The patient undergoes 24-hour Holter monitoring, which shows a sinus rhythm marked by an intermittent isolated supraventricular ectopic beat, and a period of atrial fibrillation (160-200 beats/min ...

6 Recommendations for further research. 6.1 The committee recommended further research to determine if using the lead‑I electrocardiogram (ECG) devices in primary care for people with signs or ...
