This ectopic focus becomes the predominant pacemaker of the heart. When the atrial rate is greater than 100 beats per minute, the rhythm is atrial tachycardia. If less than 100 beats per minute ...

Ectopic, originating outside of the SA ... When every other QRS complex is a premature atrial contraction, then the rhythm is referred to as “atrial bigeminy” as seen in this strip above.

Sinus rhythm resumes with increased heart rates during exercise. In an ectopic atrial rhythm, P waves are present but are a different morphology compared to the sinus P wave. Ectopic P waves are most ...

higher automaticity – ectopic beats; and re-entry – atrial tachyarrhythmia; and higher vulnerability to arrhythmia – heart rate and its variability. Most of these predictors are not ready ...

Stretch could affect trans-sarcolemmal Na+/Ca++ exchange, triggering ectopic excitation and inducing atrial and ventricular arrhythmias.3 Acute modulating factors such as haemodynamic stress, ...
