And of course Ken's comments at the bottom) An elderly obese woman with cardiomyopathy, Left bundle branch block, and chronic hypercapnea presented hypoxic with altered mental status. I do not see OMI here and all trops were only minimally elevated, consistent with either chronic injury from cardiomyopathy or with acute injury from sepsis.

After resuscitation and defibrillation , there were no more episodes of TdP. Below is the patient’s 12 lead ECG following defibrillation. The patient was diagnosed with stress cardiomyopathy. Widespread T wave inversions and prolongation of the QT interval is not uncommon in Takotsubo cardiomyopathy.

There are a number of things to look for in an ECG that can hint at arrhythmia as the cause of an apparent seizure. Arrhythmogenic cardiomyopathy Long QT syndrome Hypertrophic cardiomyopathy.

In myocardial pathology, the genesis and sustainability of ventricular arrhythmia are intricately related to the degree of LV dysfunction of any cause. Tackling SCD was in God’s domain, until the brilliance of Dr. Michel Mirowski shrunk the defibrillator and implanted it under the chest in 1980. (Dr. N Engl J Med. N Engl J Med.

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. Telemetry showed Spike-on-T phenomenon which initiated PMVT.

Cardiomyopathy Cardiomyopathy is a condition that affects the heart muscle, causing it to become enlarged, thick, or rigid. Arrhythmias (Irregular Heartbeats) Persistent abnormal heart rhythms can disrupt the heart’s pumping efficiency, eventually causing it to enlarge to maintain blood flow.

VT is the second most common presenting arrhythmia.

ABSTRACT Cardiomyopathies are a significant contributor to cardiovascular morbidity and mortality, mainly due to the development of heart failure and increased risk of sudden cardiac death (SCD). Despite improvement in survival with contemporary treatment, SCD remains an important cause of mortality in cardiomyopathies.

This is an arrhythmia until proven otherwise. In this case report the 69-year old woman ( who incidently had a history of both coronary disease and cardiomyopathy ) remained in sustained VT for 5 days without hemodynamic deterioration. He complained of days to weeks of palpitations and dyspnea. His clinic ECG is shown.
