Study Finds Advantages of Full-disclosure Mobile Telemetry Monitoring over Patch and Holter Methods to Diagnose Patients with Bradyarrhythmia

“The combination of flexible monitoring duration and continuous full-disclosure ECG data, resulted in higher diagnostic yield of bradyarrhythmia, suggesting full-disclosure MCT may provide a valuable a new approach to more accurately diagnose at-risk patients and potentially identify those requiring pacemaker implantation to prevent serious adverse events,” said Marek Dziubinski, PhD, lead author, chief technology officer and inventor of PocketECG.

Bradyarrhythmia, including unusually slow heart rate (bradycardia < 40 BPM), or blocked heart beats (2nd and 3rd degree atrioventricular blocks) and pauses, carries a significant risk of sudden cardiac death. While guidelines currently recommend the use of cardiac monitoring to evaluate patients who present with an abnormally slow heart rate, this research suggests that short-term monitoring may not be sufficient to accurately diagnose some patients, who may require an implantable pacemaker to regulate their heart rhythm.

Study Results

The retrospective study analyzed 26,567 diagnostic summary reports from full-disclosure telemetry tests recorded between Jan. 1, and Dec. 31, 2017 by US-based Medi-Lynx Cardiac Monitoring. Researchers identified 3,325 cases of bradyarrhythmia using the full-disclosure PocketECG device. 

The DY of bradyarrhythmia for continuous full-disclosure MCT monitoring for up to 30 days was:

  • 175% higher than 24 hours of continuous monitoring (Holter)
  • 37% higher than 7 days of continuous monitoring (Holter)
  • 19% higher than 11 days of  continuous monitoring (Patch)

Of the reports analyzed:

  • 618 patients were diagnosed with 2nd or 3rd degree atrioventricular block,
  • 1,223 patients diagnosed with pause > 3s,
  • 1,997 patients with bradycardia < 40 BPM.

About PocketECG:
PocketECG is one of the world’s leading online cardiac monitoring technologies. A portable device, similar to a smartphone, PocketECG streams continuous, fully labeled ECG signal for up to 30 days (, classifies every heartbeat and detects short arrhythmia episodes, including atrioventricular blocks, while providing clinicians complete access to all data, at any point during the monitoring period and allowing to substantially increase the diagnostic yield for bradyarrhythmia over the traditional MCT methods1 (transmitting fractions not full-disclosure ECG).
