Abstract
A 68-year-old man with a history of diabetes mellitus type II, hypertension and active smoking was transferred to our hospital from a nearby hospital for coronary artery bypass graft (CABG) surgery after suffering a complicated inferior wall myocardial infarction (IWMI). Post the initial angioplasty, the patient developed in-stent thrombosis and became hypotensive with a systolic blood pressure < 90 mmHg. After hemodynamic stability was achieved he was transferred to our hospital. During his stay, the cardiac monitor showed fluctuations in his blood pressure with a drop in systolic blood pressure by 10 to 15 mmHg and diastolic blood pressure by 10 mmHg when he developed atrioventricular (AV) dissociation during an idioventricular rhythm. Atrial kick, the fourth phase of ventricular diastole in the cardiac cycle is where the atria contributes to the ventricular end diastolic volume by atrial contraction. The significance of the atrial kick in the hemodynamics of the patient was captured on the cardiac monitor during the patient's stay in the cardiac intensive care unit.
