Article Synopsis
- The QT variability index (QTend VI) is linked to the risk of sudden cardiac death (SCD) in chronic heart failure (CHF), but little is known about other variability measures like QTpeak VI and Tpeak-Tend VI.
- Researchers analyzed ECGs and blood pressure from 127 CHF patients to compare these variability indexes between those who experienced SCD and those who survived, noting significant differences in their results based on left ventricular ejection fraction (LVEF).
- The findings suggest that understanding variability in the QT interval may help assess SCD risk in patients, particularly those with lower LVEF, indicating a need for further research in this area.
Article Synopsis
- Emotionally charged events, like recalling anger, can increase the risk of sudden cardiac death (SCD) by triggering changes in heart activity.
- A study assessed heart rate and QT variability in post-myocardial infarction patients and healthy controls during an anger recall test, revealing that patients exhibited higher variability indices than controls.
- The findings suggest that patients struggle to adapt to stress-induced sympathetic activity, highlighting the need for stress management strategies to reduce the risk of serious heart issues.
