Screening entire healthcare system ECG database: Association of deep terminal negativity of P wave in lead V1 and ECG referral with mortality.

ABSTRACT:

Background

Each encounter of asymptomatic individuals with the healthcare system presents an opportunity for improvement of cardiovascular disease (CVD) awareness and sudden cardiac death (SCD) risk assessment. ECG sign deep terminal negativity of the P wave in V1 (DTNP_V1) was shown to be associated with an increased risk of SCD in the general population.

Objective

To evaluate association of DTNP_V1 with all-cause mortality and newly diagnosed atrial fibrillation (AFib) in the large tertiary healthcare system patient population.

Methods

Retrospective double cohort study compared two levels of exposure (automatically measured amplitude of P-prime (Pp) in V1): DTNP_V1 (Pp from -100μV to -200μV) and ZeroPpV1 (Pp=0). An entire healthcare sys
