In general, signs and symptoms of arrhythmias may include: A fluttering in the chest . A racing heartbeat (tachycardia) A slow heartbeat (bradycardia)
Read moreHow is the QRS complex described in atrial fibrillation?
The diagnosis of atrial fibrillation is confirmed with a standard 12-lead ECG. P waves are absent, coarse “fibrillatory waves” can frequently be seen and sometimes no atrial activity can be identified. The QRS complexes are “irregularly irregular ”, with varying R-R intervals.

Read moreWhat are the ECG characteristics of atrial fibrillation?
Findings from 12-lead electrocardiography (ECG) usually confirm the diagnosis of AF and include the following: Typically irregular ventricular rate (QRS complexes) Absence of discrete P waves, replaced by irregular, chaotic F waves. Aberrantly conducted beats after long-short R-R cycles (ie, Ashman phenomenon)

Read moreWhat is considered the hallmark of atrial fibrillation?
The hallmark of atrial fibrillation is absence of P-waves and an irregularly irregular (i.e totally irregular) ventricular rate . The baseline (isoelectric line between QRS complexes) is characterized by either fibrillatory waves (f-waves) or just minute oscillations.
Read moreWhich is the distinguishing factor of atrial flutter?
In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles , so you may have four atrial beats to every one ventricular beat. Atrial flutter is less common, but has similar symptoms (feeling faint, tiredness, palpitations, shortness of breath or dizziness).
