Meningitis and high-grade, second-degree atrioventricular block in an adolescent: causal effect or coincidence?

Cardiol Young 2021 May 10:1-3. Epub 2021 May 10.

The Heart Institute, Division of Cardiology, Cincinnati Children's Hospital Medical Center, Cincinnati, OH, USA.

We describe an adolescent with Streptococcus pneumoniae meningitis and symptomatic high-grade, second-degree atrioventricular block requiring permanent pacemaker placement. It is difficult to ascertain if these two diagnoses were independent or had a causal relationship though ongoing symptoms were not present prior to the infection. Because of this uncertainty, awareness that rhythm disturbances can be cardiac in origin but also secondary to other aetiologies, such as infection, is warranted. Read More

Second-degree atrioventricular block after administration of methylergometrine for treatment of uterine atony during cesarean section.

Rev Esp Anestesiol Reanim (Engl Ed) 2021 Apr 7. Epub 2021 Apr 7.

Servicio de Anestesiología y Reanimación, Complejo Hospitalario Universitario de Canarias, San Cristóbal de La Laguna, Santa Cruz de Tenerife, España.

Mortality due to cardiovascular disease in pregnancy is a growing problem in developed countries, being nowadays the leading cause of maternal death. Within this group, the most common cause of death are congenital or acquired heart diseases, representing a challenge in the management of these patients, since the pregnancy-related physiological alterations can impair their basal condition and treatment. We present the case of a 34-year-old patient, without any relevant pathological antecedents, who developed a second-degree atrioventricular block, Mobitz type I, following the administration of methylergometrine during cesarean section due to failure to progress in labour.

Strategy of pacemaker and electrode replacement for superior vena cava stenosis.

J Int Med Res 2021 Jan;49(1):300060520945170

Department of Cardiovascular, The First Affiliated Hospital of Guangdong Pharmaceutical University, Guangzhou, Guangdong, China.

Cardiac implantable devices are commonly used for superior vena cava stenosis, but there have been few reports of electrode replacement in the stenosed superior vena cava. A 73-year-old man was diagnosed with second-degree type II atrioventricular block and a permanent dual-chamber, rate-modulated pacing pacemaker was implanted 10 years previously. Because of depletion of the pacemaker battery and an increase in the ventricular pacing threshold, replacement of the pacemaker and ventricular electrode was required. Read More

High-risk atrioventricular block in Brugada syndrome patients with a history of syncope.

J Cardiovasc Electrophysiol 2021 Mar 19;32(3):772-781. Epub 2021 Jan 19.

Department of Cardiovascular Medicine, Division of Arrhythmia and Electrophysiology, National Cerebral and Cardiovascular Center, Osaka, Japan.

Background: Determining the etiology of syncope is challenging in Brugada syndrome (BrS) patients. Implantable cardioverter defibrillator placement is recommended in BrS patients who are presumed to have arrhythmic syncope. However, arrhythmic syncope in BrS patients can occur in the setting of atrioventricular block (AVB), which should be managed by cardiac pacing. Read More

Department of Cardiology, Remin Hospital, Wuhan University, Wuhan, 430060, China.

Lorenz-RR scatter plot has an obvious shortcoming in that it does not indicate the time when the scatter point happens. On the Lorenz RR scatter plot, one cannot know the time during which the cardiac rhythms take place. Since occurrence of cardiac rhythms is time-related, time should be introduced to such plots.
