EKG with paced complexes shown below shows much narrower QRS complex and echocardiogram showed improved LV systolic function primarily due to improvement in LV dyssynchrony. (J Even with tachycardia and a paced QRS duration of ~0.16 J Am Coll Cardiol.

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. The emergent echocardiogram showed normal EF, no WMA, and normal valve function. Hopefully his outpatient EP appointment will understand and correct that.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia. Hopefully a repeat echocardiogram will be performed outpatient. The Initial ECG in Today's Case: As per Dr. Meyers — the initial ECG in today's case shows sinus tachycardia with bifascicular block ( = RBBB/LAHB ).

EMS reports intermittent sinus tachycardia and bradycardia secondary to some type of heart block during transport. It is hard to make out P waves but you can see them best in V2, and notches in the T waves in other leads - this is a sinus tachycardia with a very long PR interval indicating first degree block.

Echocardiogram was unchanged from baseline. He was counseled to abstain from cannabis use.Conclusion:At low to moderate doses, cannabis can lead to a surge in sympathetic activity causing tachycardia and hypertension, while parasympathetic activity is predominant at higher doses, causing bradycardia and hypotension.
