These are the characteristics of the normal sinus rhythm except
P wave should be a rounded shape
P-R interval should be 5-6 small square
P wave should be the same shape
The rhythm should be regular
What does ST elevation suggest?
Myocardial infarction
Heart murmur
Heart block – Mobitz type II
Bundle branch block
What is the physiological correspondence of ECG P wave occurrence?
Atrial depolarization
The depolarization wave slowly passes the AV node
Repolarization of atrium
Atrioventricular conduction
What is the physiological correspondence of ECG PR interval?
Repolarization of atrium
Represent atrial depolarization & atrioventricular conduction
Septal depolarization
Depolarization of Purkinje fibres
What is the physiological correspondence of ECG T wave?
Ventricular repolarization
Electrical diastole
Septal depolarization
Depolarization of Purkinje fibres
What is the physiological correspondence of ECG QRS complex?
Repolarization of atrium
Ventricular depolarization
Septal depolarization
Depolarization of Purkinje fibres
The sinus bradycardia
Shows irregular rhythm
Heart rate is more than 65/min
Occurs due to anxiety
Heart rate is less than 60/min
The sinus tachycardia
Shows irregular rhythm
Occurs due to suppression of SA
Saw tooth appearance
Heart rate is more than 100/min
Regarding atrial flutter
Shows irregular rhythm
Saw tooth appearance
Occurs due to suppression of SA
Heart rate is lower than 100/min
Regarding Atrial fibrillation
Conditions where atria beats rapidly and irregularly
QRS complex more than 120 mili second
There is P wave
Irregularly regular rhythm
Regarding 3rd degree heart block
Conduction from atria to ventricles partially blocked
Atrioventricular association
Conduction from atria to ventricles completely blocked
Conduction of impulses prolonged
