In‐Hospital Heart Rate Turbulence and Microvolt T‐Wave Alternans Abnormalities for Prediction of Early Life‐Threatening Ventricular Arrhythmia after Acute Myocardial Infarction

Abstract

Combined assessment of HRT and TWA showed a high predictive performance for SCD or life-threatening VA within 6 months after AMI. This combined Holter ECG index could be useful to identify high-risk patients who might benefit from early ICD implantation.

Diagnostic and prognostic values of the V-index, a novel ECG marker quantifying spatial heterogeneity of ventricular repolarization, in patients with symptoms suggestive of non-ST-elevation myocardial infarction

“…39 A recent study assessing the combined value of HRT and TWA for prediction of SCD and life threatening ventricular arrhythmias following AMI found an AUC of 0.80 for the combination of both markers. 40 The V-index in our study performed similar with an AUC of 0.82. However, thanks to the use of the information of 12-leads, the recording time needed for calculation of the V-index is only 5 minutes as opposed to 24…”

Electrocardiographic parameters effectively predict ventricular tachycardia/fibrillation in acute phase and abnormal cardiac function in chronic phase of ST‐segment elevation myocardial infarction

“…Effective predictors of VT/VF in the acute phase of STEMI are scarce. Prolonged QT interval, T‐wave electrical alternans, and PVC of short coupling interval (even R‐on‐T mode) are considered traditional risk factors for VT/VF . However these factors are not effective enough in the acute stage of STEMI.…”

Review of heart failure treatment in type 2 diabetes patients: It's at least as effective as in non-diabetic patients!

“…Moreover, in addition to HF drug optimalization, endocrinologists should verify any possible indications for ICD/CRT, as these interventional treatments are widely underused [76][77][78][79], especially in Europe [80,81]. The key question when referring patients for ICD and/or CRT implantation is whether "LV ejection fraction is ≤ 35" [82], which should be easily answerable by non-cardiologist physicians.…”
