purkinje fibre मीनिंग इन हिंदी

उदाहरण वाक्य

1. However, under some circumstances the little Purkinje fibres can depolarize and originate an atrial or ventricular premature beat.
2. They play an integral role in the electrical conduction system of the heart by transmitting cardiac action potentials to the Purkinje fibres.
3. As conduction through the myocardium is slower than conduction through the Bundle of His-Purkinje fibres, the QRS complex is seen to be widened.
4. They play an integral role in the electrical conduction system of the heart by transmitting cardiac action potentials from the bundle of His to the Purkinje fibres.
5. The impulse then spreads through both ventricles via the Bundle of His and the Purkinje fibres causing a synchronised contraction of the heart muscle and, thus, the pulse.
6. The left and right branches of this bundle, and the Purkinje fibres, will also produce a spontaneous action potential at a rate of 30-40 beats per minute, so if the SA and AV node both fail to function, these cells can become pacemakers.
