An hour later, she began to feel warm, restless, and anxious. Her husband noticed she was looking pale and said he would take her to a nearby walk-in clinic. By the time they arrived, Martha said her left arm and shoulder were sore. Suspecting Martha was having a heart attack, her husband turned the car around and rushed her to the hospital.

• The intrinsic conduction system of the heart initiates depolarization impulses. • Action potentials spread throughout the heart, causing coordinated heart contraction. • An ECG wave tracing records the electrical activity of the heart. ** Now is a good time to go to quiz questions 3 and 4:

-Leads- is a record of electrical activity between two electrodes-Frontal Plane leads- view the heart from the front of the body; there are six of these leads (I, II, III, aVR, aVL, and aVF)-Horizontal plane leads- view the heart as if the body were sliced in half horizontally at the heart; there are six of these leads (V1, V2, V3, V4, V5, and V6)

Physiology of Cardiac Conduction. In an adult with a healthy heart, the heart rate is usually about 72 beats per minute. The excitatory and electrical conduction system of the heart is responsible for the contraction and relaxation of the heart muscle. The sinoatrial node (SA node) is the pacemaker where the electrical impulse is generated.

The electrical impulses generated by the heart’s conduction system begin in the . sinoatrial node (SA node), which is located in the upper wall of right atrium (Figure 1) near the entrance of the superior vena cava. Since the heart’s electrical activity begins with the SA node, it is known as the pacemaker of the heart.

Explain the electrical conduction not the heart. Discuss the correlation of the ECG waves to the cardiac conduction. Describe the lead placement for an ECG. Calculate the heart rate from an ECG paper strip. Identify a normal sinus rhythm, sinus bradycardia, sinus tachycardia, and a sinus arrhythmia. Peripheral Vascular Disease (PVD)
The Conducting System
Understand how conduction of electrical signals through the heart can be detected as an electrocardiogram (ECG or EKG). Understand the relationships between ECGs, blood pressures, blood flows, and the opening and closing of cardiac valves.
Electrical conduction system of the heart - Wikipedia
The heart's conducting system consists of the . sinoatrial node (SA node), atrioventicular node (AV node), the bundle of His, the bundle branches and the Purkinje fibers. The electrical impulse that causes rhythmic contraction of heart muscles arises in the . SA node. which is the intrinsic pacemaker of the heart.
