Sinoatrial Node Collection

Heart chambers and sinus node, artwork C014 / 2030
Heart chambers and sinus node (yellow). Cutaway artwork revealing the four internal heart chambers and the heart valves and tendons (white). The two upper chambers are the atria

Cardiac arrhythmia with heart and ECGs
Cardiac arrhythmia. Illustration of a section through a human heart. Electrocardiogram (ECG) traces (red) show cardiac arrhythmia, the abnormal rhythm or rate of the heartbeat

Atrial fibrillation, artwork
Atrial fibrillation. Artwork of a section through a human heart during atrial fibrillation, a rapid, irregular heartbeat. Two electrocardiogram traces (ECGs) are seen at centre left and upper right

Artwork of sectioned heart with healthy ECG trace
Heart nerve conduction. Illustration of a section through a human heart with an electrocardiogram (ECG) trace. The heart is a hollow muscle that pumps blood around the body

Electrical conduction in the heart, artwork. Each heartbeat is initiated by an electrical impulse from the sinoatrial (SA) node (green oval) in the right atrium (upper heart chamber)

Illustration of electrical conduction in the heart
Electrical conduction in heart. Illustration of a human heart, showing the specialised tissue that conducts the electrical signals governing heart- beats

Atrial fibrillation. Artwork of a section through a human heart during atrial fibrillation, a rapid, irregular heartbeat. In the background are ECG (electrocardiogram) traces

Electrical conduction of the heart. Artwork showing the impulse conduction system (yellow) of the human heart (left) and an electrocardiogram (ECG) of a normal heart rate (right)
