Abstract

Ambulatory cardiac monitoring devices such as external loop recorders (ELRs) are often used in the outpatient clinic to evaluate palpitations. However, ELRs can be bulky and uncomfortable to use, especially in public, at work, or in social situations. An alternative approach is a smartphone-based electrocardiographic (ECG) recorder/event recorder (Kardia Mobile [KM]), but the comparative diagnostic yield of each approach has not been studied. Thirty-three patients with palpitations wore an ELR and carried a KM for a period of 14-30 days. They were instructed to transmit ECGs via KM and also to activate the ELR whenever they had symptoms. The tracings obtained from both devices were independently analyzed by two cardiologists, and the overall arrhythmia yield, as well as patient preference and compliance, were evaluated. The paired binomial data obtained from both devices were compared using an unconditional test of noninferiority. Of the 38 patients enrolled in the study, more patients had a potential diagnosis for their symptoms (i.e., at least one symptomatic recording during the entire monitoring period) with KM than with the ELR (KM = 34 [89.5%] vs ELR = 26 [68.4%]; χ2  = 5.1, P = 0.024). In the per protocol analysis, all 3...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.
