Changes in cardiac rhythm may occur during epileptic seizures and this has been suggested as a possible mechanism for sudden unexpected death amongst patients with chronic epilepsy (SUDEP). We have studied ECG changes during 61 complex partial seizures of temporal lobe origin in 20 patients. Tachycardia was observed in 24/61 (39%) and bradycardia in 3/61 (5%). The mean and median tachycardia ra...

BACKGROUND During the four steps of the Valsalva maneuver (VM), opposite changes can be observed in some physiologic parameters. Manifestations of the VM in the electrocardiogram (ECG) have been studied in detail, but there have been few reports comparing VM-related biochemical and hemodynamic changes with a focus on the strain phase of the VM. OBJECTIVES We studied strain-related ECG changes...

BACKGROUND In patients with Brugada syndrome (BS), ventricular fibrillation (VF) occurs mainly during sleep; therefore, not only vagal activity but also bradycardia dependent changes in ECG may relate to the nighttime occurrence of VF. The present study aimed to examine the difference in bradycardia-dependent changes in the ECG of symptomatic and asymptomatic BS patients. METHODS AND RESULTS ...

BACKGROUND Ventricular arrhythmia occurrence during exercise is reported in Brugada syndrome (BrS). Accordingly, experimental studies suggest that BrS-linked SCN5A mutations reduce sodium current more at fast heart rates. Yet, the effects of exercise on the BrS ECG phenotype have not been studied. We aimed to assess ECG responses to exercise in BrS and determine whether these responses are affe...

    Introduction: Retraining programs for nurses are usually run as workshops and group discussions causing challenges as limitations on the number of participants, long lasting duration and high costs. Since most of these programs are taught by instructors working outside of clinical setting , it is necessary to use a method to train large groups of nurses in a short time. The purpose of t his...

Twenty children with hypokalemia (plasma potassium concentration < or = 3.5 mmol/L) with electrocardiographic (ECG) changes were given an infusion of concentrated solution of potassium chloride (200 mmol/L) at a rate of 0.25 mmol per kg per hour till ECG changes reverted to normal, under close monitoring of vital signs and ECG. The regimen effectively corrected the ECG changes in 1 to 6 hours w...

Background and purpose: In ischemic state some substrates are shifted to glucose leading to less oxygen consumption. The aim of this study was to assess the effect of glucose, insulin and potassium (GIK) infusion in patients with high risk acute coronary syndrome (ACS). Materials and methods: A double-blind, pilot clinical trial was conducted in 41 high-risk ACS-NSTEMI-patients attending Em...

Various electrocardiography (ECG) abnormalities have been reported in patients who present with pulmonary embolism (PE). Severe sepsis is also associated with ECG changes that may mimic ST elevation myocardial infarction. We report a case of an elderly patient with PE and septic shock associated with striking ECG changes.

We reported two patients who presented with non-specific chest symptoms with ECG changes mimicking acute myocardial infarction and ventricular hypertrophy. Both of them were finally confirmed to have Wolff-Parkinson-White (WPW) syndrome after spontaneous resolution of the ECG changes. As a matter of fact, other differential diagnosis should be considered with respect to the ST-segment changes. ...
