A man in his 40s with acute chest pain. What do you think?

Dr. Smith's ECG Blog

It's a very "fun" ECG, with initial ectopic atrial tachycardia (negative P waves in inferior leads conducting 1:1 with the QRSs), followed by spontaneous resolution to sinus rhythm. What About the Tachycardia? Today's regular SVT rhythm could be an ectopic atrial tachycardia ( ATach ) — or an automatic junctional tachycardia.

ECG Blog #434 — WHY Did this Patient Arrest?

Ken Grauer, MD

The rhythm is regular — at a rate just over 100/minute = sinus tachycardia ( ie, the R-R interval is just under 3 large boxes in duration ). The cause of the abnormal baseline deflections seen in Figure-2 is most likely muscle tremor artifact ( See Bouthillet T — ACLS Med Training, Dec, 2015 ). Figure-2: I've labeled the initial ECG.

PO-05-062 THE GREAT VALUE OF EXTRA-CARDIAC VAGAL STIMULATION IN STUDYING VENTRICULO-ATRIAL CONDUCTION AND DIAGNOSING CONCEALED VENTRICULO-ATRIAL PATHWAYS

HeartRhythm

The study of ventriculoatrial (VA) conduction during an electrophysiological (EP) study is crucial for ablating supraventricular tachycardias (SVT) and WPW, particularly with suspected accessory pathways or AV nodal reentry tachycardia.
