Moreover, the 24-h Holter monitoring fails to detect the culprit arrhythmia in a significant proportion of symptomatic patients ( 7). Twenty-four hour Holter monitoring, introduced in the late 1940s, remains the most widely used method to detect cardiac arrhythmias in ambulatory patients ( 3) despite a low diagnostic yield, 15–40%, in this patients population ( 4– 6). Pauses and AVB were equally identified by the two devices in three patients.Ĭonclusion: Over the total wear time, the SmartCardia device showed an accuracy to detect arrhythmia similar to the 24-h Holter monitoring: single-lead, adhesive-patch monitoring might become an interesting alternative to the conventional Holter monitoring.Ĭardiac arrhythmias, such as atrial fibrillation (AF), are often asymptomatic and sometimes associated with adverse events, such as strokes and peripheral arterial embolisms ( 1, 2). Over the total wear time, there was no significant difference between the devices for ventricular and supraventricular arrhythmias detection. Results: A total of 40 patients were included in the trial. McNemar's test was used to compare the matched pairs of data from both devices. Conduction abnormalities, pause ≥2 s and atrioventricular block (AVB), were also tracked. The primary endpoint was the detection of cardiac arrhythmias over the total wear time of the devices, defined as premature atrial contraction (PAC), supraventricular tachycardia ≥3 beats, premature ventricular contraction (PVC), and ventricular tachycardia ≥3 beats. Simultaneous ambulatory ECG were recorded using a conventional 24-h Holter and the SmartCardia. Methods: Patients referred for a suspicion of arrhythmia between February and March 2020 were included in the trial.
Wireless heart monitor Patch#
Hypothesis: The accuracy of the new SmartCardia wireless patch to detect arrhythmias is comparable to the conventional Holter monitoring. The SmartCardia ScaAI wireless patch is a novel CE IIa approved, single-lead electrocardiographic (ECG) ambulatory monitor designed for cardiac arrhythmias detection. An optimization of arrhythmia detection would permit to better treat patients and could substantially reduce morbidity and mortality. 3Sir Harkisandas Narottamdas Reliance Hospital, Mumbai, Indiaīackground: Cardiac arrhythmias are very common but underdiagnosed due to their transient and asymptomatic nature.2University Hospital, Fribourg, Switzerland.1École polytechnique fédérale de Lausanne Innovation Park, Lausanne, Switzerland.Srinivasan Murali 1, Nicolas Brugger 2, Francisco Rincon 1, Manoj Mashru 3, Stéphane Cook 2 and Jean-Jacques Goy 4 *
