|---|---|---|---|---|---|
| Cardiac innervation | show 🗑
|
||||
| show | Sympathetic - faster heart rate, faster conduction velocity, stronger contraction and faster relaxation
Parasympathetic - slower heart rate, slower conduction velocity - may innervate ventricles but limited evidence
🗑
|
||||
| show | Mainly on If, Ica and Ik - these control heart rate
Increases these to give a faster pacemaker, upstroke and recovery
🗑
|
||||
| show | Can activate K channels, causing hyperpolarisation
Antagonises the sympathetic NS and opens IKACh, reducing heart rate and hyperpolarising membrane potential
🗑
|
||||
| show | Lack of stabilising Ik - more positive and alterable resting potential
Stabilised by IKACh
Early pacemaker current - If
Late pacemaker current - IcaT
Upstroke - IcaL
Recovery - Ik
🗑
|
||||
| Effect of beta receptors | show 🗑
|
||||
| Effect of muscarinic receptors | show 🗑
|
||||
| Positive ionotropic effects of sympathetic nerve stimulation | show 🗑
|
||||
| Mechanism of beta adrenoreceptor stimulation | show 🗑
|
||||
| Ionotropic effects of sympathetic nerve stimulation | show 🗑
|
||||
| Evidence that IcaL is altered by PKA | show 🗑
|
||||
| Role of protein phosphatase 2A | show 🗑
|
||||
| show | Frank starling mechanism
Increase in venous return in exercise increases ventricular stretch
This increases stroke volume and cardiac output
🗑
|
||||
| Roles of pharmacological compounds | show 🗑
|
||||
| Targets for inotropic agents | show 🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
