Heart monitoring system usable with a smartphone or computer
A personal monitoring device has a sensor assembly configured to sense physiological signals upon contact with a user's skin. The sensor assembly produces electrical signals representing the sensed physiological signals. A converter assembly, integrated with, and electrically connected to the sensor assembly, converts the electrical signals generated by the sensor assembly to a frequency modulated physiological audio signal having a carrier frequency in the range of from about 6 kHz to about 20 kHz.
1. A mobile ECG device comprising:
an electrode assembly comprising at least 3 electrodes, wherein the electrodes are to concurrently sense heart-related signals upon contact with a user's skin, and to produce electrical signals representing the sensed heart-related signals;
a converter assembly electrically connected to the electrode assembly, configured to convert the electrical signals to a modulated physiological audio signal, wherein the modulated physiological audio signal carries information representing the sensed heart-related signals; and
a wireless acoustic transmitter that directly transmits the modulated physiological audio signal wirelessly to a computing device.
2. The mobile ECG device according to claim 1 , wherein the modulated physiological audio signal is a frequency modulated physiological audio signal, wherein the wireless acoustic transmitter outputs the frequency modulated physiological audio signal having a carrier frequency in the range of from about 6 kHz to about 20 kHz.
