Partial atrioventricular

  • Sino-atrial

  • Intra-atrial

  • Intraventricular

    1. 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?

      1. Sinus tachycardia

      2. Sinus bradycardia

      3. Sinus arrhythmia

      4. Ciliary arrhythmia

      5. Extrasystole

    2. 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:

      1. Extrasystole

      2. Bradycardia

      3. Tachycardia

      4. Flutter

      5. Fibrillation

    1. 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?

      1. Atrioventricular

      2. Sinus

      3. Atrial

      4. Ventricular

      5. Bundle-branch

    1. Analysis of the ECG revealed the missing of several PQRST cycles. The remaining waves and complexes are not changed. Specify the type of arrhythmia:

      1. Sinoatrial block

      2. Atrial fibrillation

      3. Atrioventricular block

      4. Atrial premature beat

      5. Intra-atrial block

    1. 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:

      1. Ventricles

      2. Atria

      3. Atrio-ventricular node

      4. Right ventricle

      5. Left ventricle

    1. During ventricular systole, the cardiac muscle does not respond to additional stimulation because it is in the phase of:

      1. Absolute refractoriness

      2. Relational refractoriness

      3. Hyperexcitability

      4. Subnormal excitability

      5. There is no correct answer

    2. A patient complaining of pain in the left shoulder-blade region has been diagnosed with miocardial infarction. What kind of pain does the patient have?

    A. Radiating

    B. Visceral

    C. Phantom

    D. Protopathic

    E. Epicritic

    39/. A woman, who has been suffering from marked hypertension for 15 years, has lately developed dyspnea, palpitations, slightly decreased systolic pressure, while diastolic pressure remains the same What is the main mechanism of heart failure development in this case?

    A. Cardiac overload due to increased vascular resistance

    B. Cardiac overload due to increased blood volume

    C. Damage to the myocardium

    D. Disorder of impulse conduction in the myocardium
