SUMMARY
A
- > Chambers + conduction system of heart
- > Pacemaker tissues + overdrive suppression
- > cell at rest (ions + membrane permeability)
- > cell activated (ions + phases of action potential)
- > ECG (waves + intervals)
- > correspond ECG to heart contraction or relax
- > heart rate + exercise
Whole heart is constituted of myocytes; relate ‘excitation of single cardiac cell / myocyte’ to whole heart
contraction of cell results in contraction of whole heart to push blood around body and lungs.
