Background/Objectives The association between electrocardiographic abnormalities and the outcomes in acute ischemic stroke patients after intravenous thrombolysis remains unclear. We sought to assess the predictive value of electrocardiographic abnormalities in stroke patients after thrombolysis. Methods Consecutive acute stroke patients with thrombolysis from Feb 2008 to Jun 2013 were includ...

Four patients with Prinzmetal's variant angina pectoris were subjected to continuous electrocardiographic recording. In three of them several episodes of ST segment elevation unaccompanied by pain were recorded. In one patient, identical electrocardiographic alterations were observed both in presence or in absence of pain, while in the others a good correlation was evident between pain and seve...

Electrocardiograph (ECG) interpretation is a complex subject that requires considerable experience. However, an understanding of the principles underlying generation of the ECG can make this learning process easier. This knowledge is necessary if interpretation is to be founded on understanding rather than being a pattern recognition-based process. The aim of this article is to introduce the pr...

Water immersion alters the autonomic nervous system (ANS) response in humans. The effect of water immersion on executive function and ANS responses related to executive function tasks was unknown. Therefore, this study aimed to determine whether water immersion alters ANS response during executive tasks. Fourteen healthy participants performed color-word-matching Stroop tasks before and after n...

Seventy-six patients with severe (greater than 80%) occlusive left anterior descending coronary artery disease by coronary angiography were examined for the electrocardiographic characteristics of this disease in the presence (group A 59 patients) or the absence (group B 17 patients) of anterior wall asynergy (akinesis or dyskinesis). The incidence of clinically documented anterior myocardial i...

Rationale: Left bundle branch block is a diagnostic utility for ST-segment elevation myocardial infarction equivalent. Consequently, administration of thrombolytic pivotal step. Emergent Sgarbosa criteria and their modification are considered helpful guide keys. Wavy triple an electrocardiographic sign (Yasser Sign) novel in hypocalcemia. Interestingly, the presentation COVID-19 pneumonia with ...

To the Editor:—We read the excellent article by Patel and Souter regarding equipment-related electrocardiographic artifacts. We wish to remind readers of ANESTHESIOLOGY that the electrocardiographic monitor itself can also introduce artifacts, e.g., ST-segment depression, in the example described below and documented in figure 1. An asymptomatic 86-yr-old man was scheduled to undergo cataract e...
