This is a challenging ECG in regards to determining if the wide QRS complex rhythm is from ventricular tachycardia or "SVT with aberrancy" such as AV nodal reentry tachycardia causing a rate-dependent ...

T wave alternans refers to the variation of the T wave amplitude on an ECG on a beat-to-beat basis. Having significant T wave alternans is thought to increase the risk of ventricular arrhythmias and ...

Narrow-complex tachyarrhythmias are rapid heart rhythms originating in the upper heart chambers, characterized by a QRS duration of less than 120 milliseconds on an EKG. These arrhythmias can be ...

A 68-year-old man without previous comorbidities presented to the emergency department with complaints of palpitations and giddiness. On examination, his pulse rate was 92 beats per minute, and his ...

HeartBeam’s synthesised 12-lead electrocardiogram (ECG) has met the clinical endpoints in the VALID-ECG pivotal study, assessing non-life-threatening arrhythmias. In the study, the mean difference in ...

Smartwatches with both PPG and ECG functionality improve the detection of atrial fibrillation in comparison with standard care. Researchers from Amsterdam UMC have analyzed the data from 437 patients ...

A heart arrhythmia is when your heart beats too fast, too slow, or out of sync. Some arrhythmias can be genetic. A genetic arrhythmia happens when one or both of your parents pass down a gene change ...

Pre-screening is crucial for athletes to reduce the risk of sudden cardiac death (SCD). However, 12 lead ECG screening alone is insufficient to prevent SCD. Objective This study aims to determine the ...

Instead of spending time hooked up to an expensive machine at the hospital, a number of phones will monitor your heart for you, and alert the doctor if anything is going wrong. Your smartphone can ...
