Background: Electrical alternans (EA) has not been fully studied in the current percutaneous coronary intervention (PCI) procedure.
Objective: The purpose of this study was to evaluate visible EA and the morphology of ST segment during PCI.
Methods: The incidence of visible EA and ST-segment morphology were studied while the coronary artery was occluded for 20 seconds.
Background: Anticoagulation therapy is essential in atrial fibrillation (AF), and in Japan, less intense control is popular.
Purpose: To assess the efficacy and safety with a special reference to low intensity warfarin therapy.
Subjects And Methods: In 488 out of 508 patients with non-valvular AF, prothrombin time-international normalized ratio (PT-INR) was kept at 1.
Aims: The prevalence, clinical significance, and pathogenesis of J-waves were studied in the patients with an ST-elevation myocardial infarction (MI) after percutaneous coronary intervention (PCI).
Methods And Results: One hundred and fifty-two consecutive patients with an acute ST-elevation MI were included. The mean age was 68.
