Abstract
Disclosed is a method for implementation by one or more data processors including acquiring noninvasive blood pressure data using an inflatable cuff applied around a portion of a patient by inflating the cuff to a pressure above the patient's systolic blood pressure, and detecting a first oscillation pulse within the cuff during a deflation step. The method also includes acquiring electrocardiogram (ECG) data from the patient by detecting an ECG waveform corresponding to a first heartbeat using an ECG lead coupled to the patient, classifying the ECG waveform as normal or not normal, aligning, the first oscillation pulse to the ECG waveform corresponding to the first heartbeat if the ECG waveform is classified normal or rejecting the first oscillation pulse if the ECG waveform is classified not normal, and calculating the blood pressure using the aligned first oscillation pulse. Related apparatus, systems, methods and/or articles are described.
