All are effects of sympathetic stimulation, EXCEPT:
C i.e. Increased refractory periodEffect of sympathetic system on hea mediated by Pi and (ix receptorsSA nodeIncrease in hea rateA.V. nodeIncrease in conduction velocityHis- Purkinje systemIncrease in conduction velocityAtriaIncrease in contractility & conduction velocityVentriclesIncrease in contractility
Increased conduction velocity
Increased hea rate
Increased refractory period
Increased contractility of hea
