Defibrillator Dysrhythmia Tachycardia

ECG#1 There is a regular tachycardia with a ventricular rate of about 180 bpm. Smith comment : When there is a regular wide complex tachycardia, first assess whether it is sinus or not. Is it sinus or is it a supraventricular dysrhythmia? Put shortly is SVT with "Shark Fin STE" and not ventricular tachycardia.

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.

At cath, he immediately had incessant Torsades de Pointes requiring defibrillation 7 times and requiring placement of a transvenous pacer for overdrive pacing at a rate of 80. See here for management of Polymorphic Ventricular Tachycardia , which includes Torsades. Could the dysrhythmias have been prevented? Learning Points: 1.

It was reportedly a PEA arrest; there was no recorded V Fib and no defibrillation. Then there is loss of pulses with continued narrow complex on the monitor ("PEA arrest") Learning Points: Sudden witnessed Cardiac Arrest due to ACS is almost always due to dysrhythmia. CPR was initiated immediately.

Is it ventricular tachycardia (VT) due to hyperK or is it a supraventricular rhythm with hyperK? Here are other posts on hyperK, large calcium doses for hyperK, and ventricular tachycardia in hyperK Weakness, prolonged PR interval, wide complex, ventricular tachycardia Very Wide and Very Fast, What is it? How would you treat?

Otherwise vitals after intubation were only notable for tachycardia. An initial EKG was obtained: Computer read: sinus tachycardia, early acute anterior infarct. She was ventilated by bag-valve-mask by EMS on arrival and was quickly intubated with etomidate and succinylcholine. A rectal temperature was obtained which read 107.9

Smith comments : Wide complex tachycardia. The differential diagnosis of WCT is: 1) Sinus tachycardia with "aberrancy" (in this case RBBB and LAFB), but there are no P-waves and the QRS morphology is not typical of simple RBBB/LAFB. Also, if the rate is constant, not wavering up and down, it is highly unlikely to be sinus tachycardia.
