Finally, do a coronary angiogram Possible alternative to pacing is to give a beta-1 agonist to increase heart rate. 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.

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. The patient did not have underlying diseases.

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.

After resuscitation and defibrillation , there were no more episodes of TdP. A coronary angiogram was done that did not show significant coronary artery disease. Below is the patient’s 12 lead ECG following defibrillation. Post ROSC the patient was alert and cooperative. What does this ECG tell you?

The shortened PR-interval, specifically, proved to be quite beguiling as it swept crews down a differential diagnosis of intermittent accessory pathway syndrome – insomuch as a “syndrome” of recurrent tachycardia to account for the patient’s symptoms.

During observation in the ED the patient had multiple self-terminating runs of Non-Sustained monomorphic Ventricular Tachycardia (NSVT). CT coronary angiogram showed a hypoplastic RCA and dominant LCx. This patient very likely has some form of idiopathic ventricular tachycardia. No PVCs are seen.
