A patient complains of palpitation after stress. The pulse is 104 bpm, P-Q=0,12 seconds, there are no changes of QRS complex. What type of arrhythmia does the patient have?
A 67 year old patient complains of periodic heart ache, dyspnea during light physical activities. ECG reveals extraordinary contractions of heart ventricles. Such arrhythmia is called:
A 45-year-old patient was admitted to the cardiological department. ECG data:
negative P wave overlaps QRS complex, diastolic interval is prolonged after
extrasystole. What type of extrasystole is it?
Analysis of the ECG revealed the missing of several PQRST cycles. The remaining waves and complexes are not changed. Specify the type of arrhythmia:
Atrial premature beat
ECG of a patient displays an abnormally long R wave (up to 0,18s). This is caused by a decrease in the conduction velocity of the following heart structures:
During ventricular systole, the cardiac muscle does not respond to additional stimulation because it is in the phase of:
