Both arrhythmias have at least 3 different P-wave morphologies in a single ECG lead, but the heart rate is different. When the heart rate is lower than 100 beats per minute, the heart rhythm is considered wandering atrial pacemaker. When the heart rate is greater than 100 beats per minute, the heart rhythm is considered multifocal atrial ...
This sinus rhythm is important because it ensures that the heart's atria reliably contract before the ventricles, ensuring as optimal stroke volume and cardiac output. [ 4 ] In junctional rhythm, however, the sinoatrial node does not control the heart's rhythm – this can happen in the case of a block in conduction somewhere along the pathway ...
"Life in the Fast Lane" is a song written by Joe Walsh, Glenn Frey and Don Henley, and recorded by American rock band Eagles for the band's fifth studio album Hotel California (1976). It was the third single released from this album, and peaked at No. 11 on the Billboard Hot 100 .
If EPS is negative, long-term rhythm monitoring with an implantable loop recorder (ILR) is advised. [ 3 ] Most commonly, it refers to a combination of right bundle branch block (RBBB) and either left anterior fascicular block (LAFB) or left posterior fascicular block (LPFB), with the former being more common.
Electrical alternans is an electrocardiographic phenomenon of alternation of QRS complex amplitude or axis between beats and a possible wandering base-line. It can be seen in cardiac tamponade and severe pericardial effusion and is thought to be related to changes in the ventricular electrical axis due to fluid in the pericardium, as the heart essentially wobbles in the fluid filled ...
Sinus arrhythmia is a commonly encountered variation of normal sinus rhythm. Sinus arrhythmia characteristically presents with an irregular rate in which the variation in the R-R interval is more than 0.12 seconds (120 milliseconds). Additionally, P waves are typically mono-form and in a pattern consistent with atrial activation originating ...
Ectopic atrial tachycardia (EAT), also known as automatic atrial tachycardia, is an arrhythmia caused by both atria with abnormally fast atrial rates. [12] The ectopic focus's firing rate is quicker than that of the sinus node, and it overrides normal sinus node activity. Heart rates in children and adolescents can range from 130 to 210 beats ...
During normal sinus rhythm, these signals pass through only one pathway, known as the fast pathway. The fast pathway conducts signals quickly but has a longer rest period before it can send another signal. However, in people with PSVT caused by atrioventricular nodal reentry, both the fast and the slow pathways are activated. [9]
