Hourly premature atrial contractions in 24-h holter ECG monitoring of acute ischemic stroke patients: insights from the FIND-AF 2 trial
An increased number of premature atrial contractions (PACs) has been associated with an increased risk of atrial fibrillation (AF) and ischemic stroke. Prior studies used 24-hours or 48-hours of ECG monitoring and thresholds of ≥720 PACs/24 hours to define excessive supraventricular ectopy (ESVEA). To dete...
