Because she has cardiomyopathy and ventricular dysrhythmias, the pacer included an Implanted Cardioverter-Defibrillator (ICD) Echo 6 days later after CRT: Normal estimated left ventricular ejection fraction. Even with tachycardia and a paced QRS duration of ~0.16 No wall motion abnormality. J Am Coll Cardiol.

This can initiate ventricular arrhythmias like polymorphic ventricular tachycardia (PMVT). She was externally defibrillated with 200J and received magnesium and an IV amiodarone bolus. She was successfully defibrillated with 360J. Transthoracic echocardiogram showed normal biventricular systolic function.

From afar, there is gross tachycardia, cadence irregularities, and narrow QRS complexes that may, or may not, be Sinus in origin; and finally – a cacophony of wide complexes that might very well be ventricular in origin. McLaren : We’ve answered the first question – Sinus Tachycardia with episodic runs of wide QRS (RBBB morphology) and PVC’s.

Background Consensus guidelines support the use of implanted cardioverter-defibrillators (ICD) for primary prevention of sudden cardiac death in patients with either non-ischaemic or ischaemic cardiomyopathy with left ventricular ejection fraction (LVEF) ≤35%. A secondary analysis was performed for LVEF 36%–40%.

Patients with BrS can be asymptomatic or present with symptoms secondary to polymorphic ventricular tachycardia or ventricular fibrillation. The routine laboratory results, imaging study, coronary angiogram, and echocardiogram (ECG) were normal. A type 1 BrS pattern was identified in one resting ECG.

We can see enough to make out that the rhythm is sinus tachycardia. Tachycardia is unusual for OMI, unless the patient is in cardiogenic shock (or getting close). A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW.

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. A formal echocardiogram was completed the next day and again showed a normal ejection fraction without any focal wall motion abnormalities to suggest CAD.
