She was awake, alert, well perfused, with normal mental status and overall unremarkable physical exam except for a regular tachycardia, possible rales at both bases, some mild RUQ abdominal tenderness. Thus, I believe it is a regular, monomorphic, wide complex tachycardia. Or it could simply still be classic VT. What is the Diagnosis?

This provided comprehensive rhythm surveillance and automatic downloads of all detections to a monitoring station for cardiology interpretation. Those with sinus tachycardia were treated with beta-blockers and those with ventricular hypertrophy received a beta-blocker and ACE-inhibitor combination.

Details of my approach to ECG diagnosis of BBB are beyond the scope of this blog post — but are discussed in the ECG Video below ( or in free download of Section 5 PDF on BBB — from my ECG-2014-ePub ). The rhythm is sinus tachycardia at ~105/minute. The rhythm is sinus tachycardia at ~115/minute.

QUESTION: This tracing was interpreted as sinus tachycardia with some kind of BBB ( B undle B ranch B lock ). ANSWER: There is no Bundle Branch Block because the rhythm is not sinus tachycardia. Thus, one might easily be fooled from Figure-1 into thinking that todays rhythm is sinus tachycardia. What kind of BBB is this?

T wave inversion as seen in ECG #2 is not uncommon following a sustained tachyarrhythmia ( sometimes called a "Memory Effect" or "post-tachycardia" syndrome ). In most cases when not due to a new infarction this post-tachycardia T wave inversion resolves over the ensuing hours ( and almost alwlays within 1-2 days ).

While its action improves AV conduction it may increase the sinus rate, producing a sinus tachycardia with adverse effect. A DDENDUM # 2 ( 3/8/2025 ) : I've included below an Audio Pearl a Video Pearl and links for download of PDFs reviewing the ECG diagnosis of AV Blocks. However, Atropine is not benign.

Awareness of our relative certainty about whether we are dealing with ischemic or idiopathic VT vs some form of SVT vs a WPW-related tachycardia can guide us for deciding when to try vagal maneuvers, electrical cardioversion, or some form of medical therapy ( ie, Adenosine, Amiodarone, Verapamil, -Blocker, or other ).
