Cardiac manifestation of corona virus disease 2019: a preliminary report.

Background: Corona virus disease 2019 (COVID-19) is a multi-systemic illness that can present with cardiac complications. This report describes the preliminary findings of cardiac manifestations seen in patients managed in three centres in Lagos, Nigeria.

Methods: Ten patients, part of an ongoing study of patients admitted in three centres in Lagos, Nigeria, with COVID-19 diagnosed with reverse transcriptase polymerase chain reaction (RT-PCR) or serology were retrospectively studied for cardiac manifestations.

Prevalence of ventricular arrhythmias and heart rate variability pattern in chronic heart failure.

Aims And Objectives: This study was carried out to determine the prevalence of ventricular arrhythmias and heart rate variability pattern in patients on treatment for chronic heart failure.

Patients And Methods: Twenty four hour ambulatory electrocardiograms were recorded in 60 patients with chronic heart failure and echocardiography left ventricular ejection fraction of less than 45%.Sixty age and sex- matched individuals with no obvious evidence of underlying cardiac disease were also evaluated for comparison.
