Key result
NUVANT system monitoring showed similar arrhythmia presentation between US and Indian patients, though atrial fibrillation was more prevalent in the US and utilization was 50% higher in India.
Why the study?
Does the prevalence of arrhythmias detected by mobile cardiac telemetry differ between US and Indian patient populations?
Cross-Sectional (n=3,284)
Yes
Does the prevalence of arrhythmias detected by mobile cardiac telemetry differ between US and Indian patient populations?
Arrhythmia profiles detected by mobile cardiac telemetry differ between US and Indian patients, with higher AFib/flutter in the US and higher ectopic rhythms, SVT, and device utilization in India.
Regional arrhythmia detection differences by mobile telemetry should not yet alter practice; leaves open need for population-specific validation.
The Corventis NUVANT™ Mobile Cardiac Telemetry System provides continuous monitoring of symptomatic and asymptomatic cardiac abnormalities to help physicians diagnose and treat non-lethal cardiac arrhythmias. Analysis of a sample of 2231 US and 1053 Indian NUVANT patients has revealed interesting statistics on the prevalence of various cardiac arrhythmias in the patient populations of the two nations. The population is non-randomized and consists of US patients where often a traditional Holter Monitor study was negative and self-pay Indian patients. Mean age was 61.3 for the US and 57.8 for India with 57% of US patients and 32% of India patients being female. Presentation of specific arrhythmia types was similar across populations with the exception of atrial fibrillation and flutter being more prevalent in the older US population as well as increased prevalence of symptomatic atrial and ventricular ectopic rhythms in all patients and SVT for female patients in India. Utilization as defined by the number of patient triggers was 50% higher for Indian patients.

Engel et al. (2014) conducted a cross-sectional in Cardiac arrhythmias (n=3,284). US patient population vs. Indian patient population was evaluated on Prevalence of various cardiac arrhythmias. NUVANT system monitoring showed similar arrhythmia presentation between US and Indian patients, though atrial fibrillation was more prevalent in the US and utilization was 50% higher in India.
