Changes in the electrocardiogram induced by coronary artery bypass grafting

摘要

ECG recordings of coronary artery bypass grafting (CABG) surgery patients have been collected: number of patients 20 (men 95%, age 64.4??8.4), records duration 10???15 minutes. The number of bypasses for each individual is from 1 to 4 (40% of the patients are with 4). ECG recordings are pre- and post-surgery, from 2 to 10 days after intervention. All parameters were measured on an average P-QRS-T interval in order to avoid accidental events or noise.
