Oscillometric non-invasive blood pressure measurements in patients experiencing abnormal heartbeats

A system comprising:

• a noninvasive blood pressure monitor to provide noninvasive blood pressure data;
• an electrocardiogram sensor to provide electrocardiogram data;
• at least one data processor;
• memory, coupled to the at least one data processor, storing instructions, which when executed, cause the at least one data processor to perform operations comprising:
• acquiring noninvasive blood pressure data using the noninvasive blood pressure monitor, and detecting a first oscillation pulse;
• acquiring electrocardiogram (ECG) data from the electrocardiogram sensor by detecting an ECG waveform corresponding to a first heartbeat using an ECG lead;
• 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.

A non-transitory computer program product storing instructions, which when executed by at least one data processor of at least one computing system, implement operations comprising:

• acquiring noninvasive blood pressure data using an inflatable cuff a lied 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;
• 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.
