Clinical utility of ambulatory ECG monitoring and 2D-ventricular strain for evaluation of post-COVID-19 ventricular arrhythmia

BMC Cardiovascular Disorders
Background A relatively common complication of COVID -19 infection is arrhythmia. There is limited information about myocardial deformation and heart rate variability (HRV) in symptomatic post COVID patients presented by ventricular arrhythmia.

Estudio de los mecanismos de las arritmias cardiacas mediante modelado y procesado robusto digital de señal [PDF]

, 2008
Las arritmias cardiacas son alteraciones del funcionamiento eléctrico normal del corazón. Algunas, las arritmias patológicas, son potencialmente malignas y constituyen una de las principales causas de mortalidad en el mundo occidental.

Unveiling the Microvasculature: The Index of Microcirculatory Resistance and Its Expanding Role in Cardiovascular Care

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Index of microcirculatory resistance (IMR) is a cutting‐edge, wire‐based tool that advances the capability assessment of coronary microvascular function. By utilizing distal coronary pressure and mean transit time under maximal hyperemia, IMR delivers consistent, reproducible insights into the microvasculature's dynamic health.

Cerebrovascular Events in Aortic Stenosis: From Native Valve Disease to TAVR‐Specific Risk and Prevention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.

Usefulness of non-contact mapping for catheter ablation of ventricular tachycardias originating at the right ventricular outflow tract

Journal of Arrhythmia, 2014
Background: Different QRS morphologies are often observed in idiopathic ventricular tachycardias or premature ventricular contractions originating from the right ventricular outflow tract (RVOT).

Potassium and ventricular arrhythmias

The American Journal of Cardiology, 1990
Potassium is a major determinant of the electrophysiologic properties of the myocardial membrane, and it plays an important role in the occurrence of arrhythmia. Hypokalemia has been associated with an increased frequency of ventricular premature complexes (VPCs) in some studies of hypertensive patients treated with diuretics, but other studies have ...

Automated diagnosis of arrhythmia using combination of CNN and LSTM techniques with variable length heart beats

Comput. Biol. Medicine, 2018
Arrhythmia is a cardiac conduction disorder characterized by irregular heartbeats. Abnormalities in the conduction system can manifest in the electrocardiographic (ECG) signal.

Role of Neuroimaging Before Coronary Angiography in Patients With Out‐of‐Hospital Cardiac Arrest

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Patients presenting following out‐of‐hospital cardiac arrest (OOHCA) often require emergency coronary angiography. Presentations can be associated with syncope or head‐trauma. Aims We investigated the impact and utility of pre‐coronary angiography CT‐Brain (CT‐B) in patients following OOHCA on clinical outcomes.
