Heart Rate Turbulence: A Review
Author Information
Author(s): Watanabe Mari A
Primary Institution: Institute of Biomedical and Life Sciences, Glasgow University
Hypothesis
Heart rate turbulence (HRT) can predict mortality and sudden cardiac death following myocardial infarction and may be applicable to other cardiac diseases.
Conclusion
HRT is a promising non-invasive method for assessing cardiac autonomic function and predicting mortality in patients at risk.
Supporting Evidence
- HRT can predict mortality after myocardial infarction.
- Combined TS and TO is the most powerful risk stratifier.
- HRT is applicable to patients on beta-blockers.
Takeaway
Heart rate turbulence is like a heartbeat rollercoaster that can help doctors figure out if someone is at risk of heart problems after a heart attack.
Methodology
The review summarizes existing literature on heart rate turbulence, including studies and clinical trials.
Limitations
HRT cannot be measured in patients without ventricular premature contractions or those with atrial fibrillation.
Participant Demographics
The study involved survivors of acute myocardial infarction, with a mean follow-up period of 20.3 months.
