A blood pressure analyzer comprised of an interconnected pressure sensor, a signal processor, a microprocessor, and a display. The microprocessor is also connected to memory and a computer transmission interface. The signal processor consists of a first signal amplifier, a low pass filter, a second signal amplifier, a high pass filter, a voltage clamp, a comparator, a third signal amplifier, an accumulator circuit, and a crystal oscillator. The analyzed and calculated systolic and diasystolic blood pressure values are shown on the display and, furthermore, accurately represents pulse wave form fluctuations to afford the user a complete understanding of blood pressure conditions and thereby provide physicians a reference for the diagnosis of cardiovascular changes.
