Master Coordination of the Cardiac Cycle fast ⚡ – clear explanations, supportive visuals, OCR-aligned.
You’ll cover
• What myogenic control of the heart means and why the heart beats without nervous input.
• The role of the sinoatrial node (SAN) as the natural pacemaker.
• How electrical impulses pass through the atrioventricular node (AVN), bundle of His and Purkyne fibres.
• How electrical coordination ensures atrial contraction occurs before ventricular contraction.
• How heart rate can be modified by nervous and hormonal control.
• How electrical activity links to mechanical contraction during the cardiac cycle.
What’s included
• Clear, labelled diagrams showing the heart’s conduction system.
• Structured tables outlining the location and function of SAN, AVN, bundle of His and Purkyne fibres.
• Visual explanations linking electrical impulses to contraction timing.
• Electrocardiogram (ECG) diagrams showing P wave, QRS complex and T wave.
• Tables linking ECG features to stages of the cardiac cycle and common conditions.
• Integrated Wiggers diagram showing pressure, volume and electrical changes through one heartbeat.
• Concise spec reminders embedded alongside diagrams and tables to reinforce key OCR wording and expectations.
