A Correlational Study Between Coupling Interval Ratio and Symptoms in Patients With Idiopathic Ventricular Premature Complexes in 24 HRS Holter Monitoring

Background and objective:Ventricular premature complexes (VPCs) are the most common arrhythmia encountered in cardiology OPD. Patients with frequent VPCs are often symptomatic. Our study aims to identify the ECG predictors of symptoms in patients with idiopathic VPCs in 24 hours Holter monitoring. Subjects and methods: This study was conducted on 102 patients with VPCs during the period of February 2019 to December 2019 in cardiology OPD of our centre.All the patients were screened with transthoracic echocardiography.24 hours Holter monitoring was done, the measured parameters were QRS width (Both in sinus beat & VPC), coupling interval (CI),CI ratio (CL/sinus cycle length) and VPC burden (Number and percentage of VPCs per day). Results:Both group had similar categorical age group and gender.ORS width of both sinus beat (P = 0.389) and VPCs (P = 0.035), VPC CI (P=0.487) and VPC burden (P = 0.458) did not correlate with symptoms but VPC CI ratio were significantly higher in Group B(symptomatic) than in group A (P = 0.004) Conclusion:There is a relationship between VPC related symptoms and VPC CI ratio.
