Conductive system of the heart:

Sinus tachycardia:

This is an increase in heart rate from 90-100 to 140 in 1 min while maintaining the correct sinus rhythm. The main ECG signs:

1.The P wave in all cycles precedes the QRS complex, its form is constant in each assignment.

2.The duration of the P-Q (R) interval is the same during all complexes.

3.Interval R-R (respectively intervals R-R) shortened due to shortening of diastole (interval T- R).

4.Displacement of the R (S) -T segment downward from isoelectric line (with a pronounced tachycardia).

Sinus tachycardia:

Sinus bradycardia:

This is a decrease in heart rate less than 60 in 1 min. (50-40) while maintaining sinus rhythm.

The main ECG signs:

1.The P wave in all cycles precedes the QRS complex its form is constant in each assignment.

2.The duration of the P-Q (R) interval is the same during all complexes.

3.R-R intervals (correspondingly R-R intervals) lengthened due to the diastolic interval T-P.

4.Slight rise of the R (S) -T segment over

isoelectric line (with a pronounced bradycardia).
