PURPOSE: To investigate the prevalence of electrocardiographic abnormalities in patients with ischemic stroke (IS), subarachnoid hemorrhage (SAH), and intracerebral hemorrhage(ICH).
METHODS: The patients included 94 men and 75 women, mean age 67 years, with IS, 56 men and 44 women, mean age 61 years, with ICH, and 36 men and 65 women, mean age 51 years, with SAH without chest pain or evidence of recent myocardial infarction. All diagnoses were confirmed by magnetic resonance imaging or brain computed tomography. Twelve-lead electrocardiograms were taken at the time stroke was diagnosed and interpreted by a cardiologist experienced in interpreting electrocardiograms.
RESULTS: Deep T wave inversion in the precordial leads was present in 0% of IS, 5% of SAH, and 5% of ICH patients. ST-segment depression was present in 17% of IS, 17% of SAH, and 26% of ICH patients. Left ventricular hypertrophy was present in 14% of IS, 8% of SAH, and 22% of ICH patients. Old Q-wave myocardial infarction was present in 23% of IS, 6% of SAH, and 20% of ICH patients. Supraventricular tachyarrhytmias were present in 17% of IS, 2% of SAH, and 6% of ICH patients. Ventricular arrhythmias were present in 6% of IS, 5% of SAH, and 5% of ICH patients. Left or right bundle branch block was present in 10% of IS, 6% of SAH, and 9% of ICH patients. Other conduction abnormalities were present in 8% of IS, 7% of SAH, and 9% of ICH patients.
CONCLUSION: Patients with IS, SAH, and ICH have a high prevalence of electrocardiographic abnormalities.
CLINICAL IMPLICATIONS: Patients with SAH or ICH have a 5% prevalence of deep T wave inversion in the precordial leads not due to acute myocardial infarction.
