Effects of atrial fibrillation on the arterial fluid dynamics: a modelling perspective [PDF]

Meccanica, published online June 2018, 2018
Atrial fibrillation (AF) is the most common form of arrhythmia with accelerated and irregular heart rate (HR), leading to both heart failure and stroke and being responsible for an increase in cardiovascular morbidity and mortality. In spite of its importance, the direct effects of AF on the arterial hemodynamic patterns are not completely known to ...

Brief remission of cardiac conduction defect under anaesthesia during trans-sphenoidal pituitary surgery [PDF]

, 2023
Acromegaly can cause paroxysmal arrhythmia and bundle branch blocks, which may or may not be symptomatic. Physiological stress induced by anaesthesia can exacerbate cardiac problems; nevertheless, reversal of such problems can also occur despite being ...

Roof‐dependent atrial flutter with epicardial conduction pathway masked by left atrium posterior wall debulking ablation

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
The 3D map shows a scarred area in the left atrial posterior wall. The left atrial posterior area and mitral isthmus line act as obstructions in the tachycardia. Propagation apparently shows a centrifugal pattern from LA inferoseptal area (yellow arrows).

New Onset Dyspnea in a Patient with Pacemaker, What Does the ECG Tracing Show? [PDF]

Dual chamber pacemakers are programmed to allow for AV synchrony. Whenever a patient with a dual chamber pacemaker with underlying sinus rhythm presents with AV dissociation, the lack of AV synchrony should be questioned.

Regional blood flow during cardiopulmonary resuscitation in dogs [PDF]

, 1980
To determine differences in regional blood flow during cardiopulmonary resuscitation (CPR) versus normal cardiac function, we measured regional blood flow to sev~ral organs in 19 pentobarbital-anesthetized dogs (6-12 kg). Regional blood flow was measured

Microvolt T‐wave alternans in early repolarization syndrome associated with ventricular arrhythmias: A case report

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Microvolt T‐wave alternans (MTWA) is a marker for the development of ventricular arrhythmias (VA), but its role in early repolarization (ER) syndrome remains unknown. MTWA was detected in a 90‐second 6‐lead electrocardiogram from an ER syndrome patient. On average, MTWA was 50 μV, higher than what was observed on healthy subjects.

Atrial Imaging and Cardiac Rhythm in Cryptogenic Embolic Stroke: The ARIES Study

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background Unknown cardioembolic sources are frequent causes of cryptogenic stroke. We analyzed the risk of atrial fibrillation (AF) or high burden of ectopic atrial activity (HBEA) in patients with cryptogenic stroke, assessing atrial function and 1 ...

Can smartphone wireless ECGs be used to accurately assess ECG intervals in pediatrics? A comparison of mobile health monitoring to standard 12-lead ECG [PDF]

, 2018
BACKGROUND:Arrhythmias in children are often paroxysmal, complicating the ability to capture the abnormal rhythm on routine ECG during an outpatient visit. The Alivecor Kardia Mobile (KM) device is a wireless mobile health (mHealth) device that generates

P21‐Activated Kinase 2 as a Novel Target for Ventricular Tachyarrhythmias Associated with Cardiac Adrenergic Stress and Hypertrophy

Advanced Science, EarlyView.
Ca2+/calmodulin‐dependent kinase II (CaMKII) activation is likely driven by oxidative stress, particularly excessive reactive oxygen species (ROS) production. This study identifies P21‐activated kinase 2 (Pak2) as a novel regulator of ROS‐induced CaMKII activation and abnormal Ca2⁺ dynamics in acute adrenergic and chronic pressure‐overload stressed ...

Computerized electrocardiogram data transformation enables effective algorithmic differentiation of wide QRS complex tachycardias

Annals of Noninvasive Electrocardiology, Volume 28, Issue 1, January 2023., 2023
Accurate automatic wide QRS complex tachycardia (WCT) differentiation may be accomplished through the use of novel parameters derived from computerized data of the (i) WCT electrocardiogram (ECG) alone and (ii) paired WCT and baseline ECGs. Once automated WCT differentiation models are integrated into commercially available computerized ECG ...
