Discontinue all negative chronotropic agents, since the risk of torsade is much higher with bradycardia or pauses. As described above by Dr. Smith Pacing in today's case is an effective intervention as doing so prevents the bradycardia and pauses that are likely to precipitate additional episodes of Torsades de Pointes.

EMS reports intermittent sinus tachycardia and bradycardia secondary to some type of heart block during transport. The echocardiogram showed a normal EF without any abnormalities. The "good news" ( from an arrhythmia interpretation perspective ) — is that we now see P waves much better than we did in the initial ECG.

Hopefully a repeat echocardiogram will be performed outpatient. Other Arrhythmias ( PACs, PVCs, AFib, Bradycardia and AV conduction disorders — potentially lethal VT/VFib ). NOTE: Prediction of cardiac contusion "severity" on the basis of cardiac arrhythmias and ECG findings — is an imperfect science. QTc prolongation.

Additionally, his cardiac telemetry monitor showed runs of accelerated idioventricular rhythm, a benign arrhythmia often associated with coronary reperfusion. Additionally, a bedside echocardiogram showed no wall motion abnormality and normal LV function. He had multiple episodes of bradycardia and nonsustained ventricular tachycardia.

The diagnosis was a bit hard to find in the chart, and the echocardiogram did only stated "assymetric hypertrophy." I added, "Makes me wonder if this could be myocarditis in a younger adult — maybe even with sinus arrhythmia." It turns out that she has hypertrophic cardiomyopathy.

Due to limitations of echocardiogram in evaluating the right ventricle, magnetic resonance imaging study of the right ventricle along with that of the left ventricle has been reported. Athlete’s bradycardia due to increased parasympathetic tone and decreased sympathetic tone is a well-known observation.
