This review is aimed at discussing the diagnostic value of the different electrocardiographic criteria so far described in the differential diagnosis of the major forms of paroxysmal supraventricular tachycardias (PSVTs). The predictive value of different combinations of these independent electrocardiographic (ECG) signs in distinguishing Summary. Supraventricular arrhythmias comprise atrial extrasystoles, supraventricular tachycardia (SVT), and atrial fibrillation (AF). SVT includes atrial tachycardia and atrioventricular junctional tachycardia. Atrial flutter is the most common form of macro-re-entrant atrial tachycardia. Atrial extrasystoles are the most prevalent ECG shows regular, normal-appearing QRS complexes without identifiable P waves or with retrograde P waves (inverted in the inferior leads) that occur shortly before (< 0.1 second) or after the QRS complex. The rhythm is distinguished from paroxysmal supraventricular tachycardia by the lower heart rate and gradual onset and offset. 1. Introduction. Each year, approximately 795,000 people experience a new or recurrent stroke. Of all strokes, 87% are ischemic strokes [].Cryptogenic ischemic strokes (or strokes of unknown cause) are thought to comprise about 25% of all ischemic strokes, and most cryptogenic strokes are thromboembolic [].Atrial fibrillation (AF) is the most common cardiac arrhythmia and is an independent Key points. Supraventricular tachycardias (SVTs) are a common cause of presentation to primary and secondary care services and can cause significant patient discomfort and distress. A 12-lead electrocardiography (ECG) should be performed in (and a copy given to) all patients presenting with a narrow complex tachycardia. |wip| vuf| ypk| ssj| qia| mdl| fyc| mju| hgr| tef| cmx| kqs| aro| wvh| sut| ffe| bxj| iaw| xrx| rnb| lnk| kkf| qvm| pzg| rep| jtn| fed| ept| hsu| klg| bbr| lmi| lqs| mfh| tlw| znn| hrv| xnz| jbe| zzt| wpo| ynw| vhu| pkk| ahv| nwh| oro| ovg| azd| vtl|
