Critical care nurses' knowledge of cardiac rhythm strips
… ACLS-certified are able to accurately interpret cardiac rhythms. Patricia Benner's model of skill acquisition was used as the theoretical framework. Critical care nurses who are ACLS-certified are assumed to be in at least the competent level of skill acquisition; The sample was comprised of 99 …

Exercise-Associated Cardiac Rhythm Disorders in Thoroughbred Racehorses
Cardiac arrhythmias negatively impact horseracing through concerns for horse and jockey safety and welfare. The most clinically relevant rhythm disorders in Thoroughbred racehorses (TBs) are atrial fibrillation (AF), which typically causes poor performance, and fatal arrhythmias which precipitate …

Automated Cardiac Rhythm Diagnosis for Electrophysiological Studies, an Enhanced Classifier Approach
INTRODUCTION Heart function can be impaired by rhythm disturbances (cardiac arrhythmia), illustrated by electrocardiogram (ECG) recordings. Computerised arrhythmia diagnosis is well established for ECG’s but less for intracardiac electrophysiological (EP) testing. Accurate diagnosis is …

AMPK-MEDIATED LONG-TERM REGULATION OF HCN4CONTRIBUTES TO AGE-RELATED SINUS BRADYCARDIA
… to the regulation of neuronal excitability and cardiac rhythm. Among the HCN isotypes, HCN4 stands out for its prominent role in pacemaker activity in the heart where it acts as a key element for the heart rhythm and its adrenergic modulation. Changes in HCN4 activity or in its amount leads to …

A comparison of two bathing methods : Effects on the haemodynamic and subjective responses of low risk patients within 48 hours post myocardial infarction
… rate pressure product (RPP), blood pressure, cardiac rhythm, ST segment changes, arterial oxygen consumption (Sa02) and chest pain. Each of these responses was measured prior to, during, immediately afterwards and 5 minutes after each bathing method. Ratings of perceived exertion and a short …

Atrial Fibrillation In Middle-Eastern Arabs And South Asians: Studies From A 20-Year National Registry In Qatar
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice accounting for approximately one-third of hospitalizations for cardiac rhythm disturbances and is associated with increased risk for stroke, heart failure and death. The epidemiology and clinical features of AF …

Does acute hypoxia and high altitude exposure adversely affect cardiovascular performance?
… hypotheses 1. HA adversely affects biventricular cardiac function leading to an increase in estimated filling pressures which is influenced by the mode of hypoxia. 2. HA exposure leads to myocardial injury that is linked to the development of AMS. 3. HA exposure is associated with a reduction in …
