Symptomatic Bradycardia in Covid-19 Hospitalized Patients: A Case Series.

SARS COV-2 infection has become a global threat. Cardiovascular manifestations associated with Covid-19 have been noted in several publications, and bradycardia related to Covid-19 is a commonly reported complication. This study reports six serial cases of bradycardia attributable to Covid-19; four of them developed complete atrioventricular block. These patients experienced clinical symptoms related to bradycardia and initially required permanent pacemaker implantation. However, one patient did not require permanent pacing later on due to spontaneous conversion to sinus rhythm. In comparison, the other two patients who developed transient sinus bradycardia experienced a self-limiting condition during their hospitalization period without requiring any cardiac pacing device or medication to increase heart rate. Complete atrioventricular block and transient sinus bradycardia in these patients, despite not having any history of bradycardia, might be due to complex processes in the systemic inflammatory response in Covid-19. Cardiac monitoring, hemodynamic evaluation, and strategy for permanent pacemaker in these patients should be treated on a case-by-case basis.

Telemedicine for detecting Brugada Syndrome in eastern Indonesia: A multi-center prospective observational study.

BACKGROUND: The incidence of Brugada syndrome has been reported to occur mostly in Asian countries. However, key countries such as Indonesia, the largest-populated Southeast Asian country, have yet to report any existing data regarding the incidence of Brugada syndrome among its population. Detecting these patients has been challenging, especially in primary healthcare settings, which generally have limited resources. Telemedicine may represent an ideal solution for initial diagnosis to determine if a patient may have this condition. METHODS: We collected and analyzed numerous 12-lead electrocardiograms (ECG) of patients who visited various healthcare centers in Makassar for routine medical check-up between June 2017-April 2018. Electrocardiograms from these centers were sent to the Cardiac Center at Dr. Wahidin Sudirohusodo Hospital in Makassar via telemedicine. RESULTS: During the period, we successfully obtained 9558 ECGs. While none of the patients were initially suspected of Brugada Syndrome, we found 102 (1.07%) among them to have a Brugada ECG pattern (BrEP). BrEP was more commonly found in males compared to females (67.6% vs. 32.4% of the cases found). There were significant differences in the number of confirmed cases among the types of BrEP for male and female patients. The number of confirmed cases of BrEP in male and female patients were significantly different (p < 0.05), where the number of cases for male vs. female was 8 vs. 4 for type 1, 17 vs. 1 for type 2, and 44 vs. 28 for type 3. CONCLUSION: Brugada syndrome is a disease that is at grave risk of being frequently underdiagnosed. Our study indicates that telemedicine can become an appropriate tool that can assist physicians in detecting suspected patients. Future efforts should also be directed at studying the possible use of telemedicine for detecting other similarly rare conditions.
