Recent advancements in catheter ablation for structural ventricular tachycardia (VT), such as high-density mapping and cardiac imaging-based detection of target areas, have significantly improved the efficacy of ablation procedures. These developments are likely to broaden the treatment scope to include patients with recurrent VT episodes.

Progressive decline across periods in mortality rates among patients with implantable cardioverter-defibrillator (ICD). Chagas disease (ChD) was associated with increased rates of ventricular tachycardia and ventricular fibrillation in ICD patients only in the initial two periods, but there was no statistical difference in the last period.

The above ECGs show the initiation and continuation of a polymorphic ventricular tachycardia. Polymorphic ventricular tachycardia can be ischemic, catecholaminergic or related to QT prolongation. She spontaneously converted (Defibrillation was not performed). Takotsubo cardiomyopathy is not a completely benign disorder.

Background Consensus guidelines support the use of implanted cardioverter-defibrillators (ICD) for primary prevention of sudden cardiac death in patients with either non-ischaemic or ischaemic cardiomyopathy with left ventricular ejection fraction (LVEF) ≤35%. vs 65.4%, p<0.0001), more often white (87.5% to 1.15, p=0.482).

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a disease characterised by fibrofatty replacement of the ventricular myocardium due to specific mutations, leading to ventricular arrhythmias and sudden cardiac death. Additionally, the impact of sotalol and amiodarone is inconsistent with studies reporting contradictory results.

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.

She was successfully revived after several rounds of ACLS including defibrillation and amiodarone. An Initial ECG was performed: Initial ECG: Sinus tachycardia with prolonged QT interval (QTc of 534 ms by Bazett). On arrival to the ED the patient was intubated with normal vital signs. No ischemic ST changes. Teaching Points: 1.

Ultimately the patient underwent implantation of secondary prevention implantable cardioverter-defibrillator and initiation of sotalol.Discussion:The prevalence of MAD is approximately 30% in those with MVP and 8% in the general population. Those patients with MAD and MVP appear to be at higher risk for VA and SCD.

There is a run of polymorphic ventricular tachycardia — which given the QT prolongation, qualifies as Torsades de Points ( TdP ). This episode self terminated before defibrillation was possible. Potassium chloride drip was also started.

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.
