Complete heart block in patients infected with SARS-CoV-2: A case series from a developing country

Abstract

Coronavirus Disease 19 (COVID-19) has led to a global pandemic and has been the center of attention across the entire medical community. This novel virus was initially thought to affect primarily the respiratory system, but now it is evident that it has a multitude of effects on the human body. Our point of interest is to establish the effect of COVID-19 infection on the conducting system of the heart. We present a case series of four patients who developed complete heart block (CHB) shortly after being infected with COVID-19 without any previous known risk factors of complete heart block. There have only been a few previous case reports on the occurrence of CHB in COVID-19 patients highlighting the importance and the need of our case series to the literature of cardiovascular outcomes in COVID-19 patients. Our case series highlight that COVID-19 can indeed affect the conduction system of the heart and cause CHB in patients who then recovered spontaneously further elucidating the transient nature of cardiovascular effects caused by the novel virus.

Characteristics of bradyarrhythmia in patients with COVID‐19: Systematic scoping review

“…Table 2 presents the baseline demographics, diagnostic findings, and chief features of COVID‐19 patients who developed bradycardia from the individual cases compiled ( n = 59) 21–52 . Bradycardia predominated in male patients ( n = 37) with a median age of 58.0 years old (IQR 48.0−71.0).…”

Bradycardia was most often observed in patients classified as having severe or critical illness COVID‐19 (35.6% and 32.2%, respectively).…”

Bloqueo auriculoventricular de tercer grado: caso clínico

“…Un dato interesante revela que, los médicos e investigadores a nivel mundial han explorado las secuelas cardiovasculares de la infección por Covid-19 Lao et al (2022). Sharif et al (2021). aseveran que en un inicio se pensó que esta pandemia afectaba principalmente al sistema respiratorio, sin embargo, en la actualidad existe evidencia científica que tiene una multitud de efectos en el cuerpo humano, incluido el sistema de conducción del corazón que puede causar un BCC.…”
