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. The septum is punctured with the active fixation screw of the lead - so essentially you bore the septum with the screw helix."

Is it sinus or is it a supraventricular dysrhythmia? After amiodarone and several defibrillations and about 20 minutes after initial arrest, stable ROSC was achieved. If rapid, that means that the depolarization is rapidly advancing and that it must be using conducting fibers (Purkinje fibers), and is therefore supraventricular.

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. Could the dysrhythmias have been prevented? Severe hypokalemia in the setting of STEMI or dysrhythmias is life-threatening and needs very rapid treatment.

The limb lead abnormalities appear to be part of the Brugada pattern, as described in this article: Inferior and Lateral Electrocardiographic RepolarizationAbnormalities in Brugada Syndrome Discussion Brugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias.

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? I could find very little literature on the treatment of severe life-threatening hypokalemia.

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.

Sinus tach is often misinterpreted as a dysrhythmia. Second , when you have a rhythm problem, you are likely to be able to fix the problem with electricity (cardioversion, defibrillation, pacing). They often have good ejection fraction and tolerate the dysrhythmia quite well. 2) PSVT with "aberrancy" (atypical RBBB+LAFB).
