PAP by ECG

Medical application is intended for Express diagnosis of Mean Pulmonary Artery Pressure (MPAP).
Using the phone's camera reads the voltage (amplitude) of teeth ECG in leads AVR, V2, V5.
Then by mathematical formula (a modification of the formula Makarenko 2002) calculated the MPAP.
The results of the calculation of pulmonary pressure by ECG correlate with the ultrasonic method of research, but are approximate and do not replace classical methods of research.
Calculation the MPAP by ECG is not possible when a complete bundle branch block.
