6. Purkinje fibers carry the impulse to the heart apex & ventricular walls. Extrinsic Innervation of the Heart • Heart is stimulated by the sympathetic cardio-acceleratory center • Heart is inhibited by the parasympathetic cardio-inhibitory center. Electrocardiography. Electrical activity is recorded by electrocardiogram (EKG)

The diagram shows a human heart as seen from the front. The main blood vessels are labelled D to G. The arrows show the pathways taken by the electrical activity involved in coordinating the heartbeat in the cardiac cycle. (a) Which of the blood vessels, D. to . G (i) carries oxygenated blood to the heart (1)

The monosyllables describing the heart sounds are 1 . The first heart sound is a result of closure of the 2 valves, whereas the second is a result of closure of the 3 valves. The heart chambers that have just been filled when you hear the first heart sound are the 4 , and the chambers that have just emptied are the 5 .

As previously mentioned, the heart has a very coordinated contraction cycle, the result of electrical signals. These electrical events may be examined in a noninvasive manner, by surface electrodes. 1. Verify that the physiograph input switch is set to the EKG and examine the electrode plug area noting the G1, G2 and GRN plugs. 2.

Electrical signals of the heart
Figure 2. Components of the human heart involved in conduction. The cardiac cycle involves a sequential contraction of the atria and the ventricles. The combined electrical activity of the different myocardial cells produces electrical currents that spread through the body fluids.

An electrocardiogram (EKG) is a graphical tracing of the electrical events that occur within the heart cycle. An EKG consists of three waves: P wave, QRS wave and T wave. The P wave is the depolzarization of the atria. The QRS wave is the depolarization of the ventricles. The T wave is the repolarization of the ventricles.

As the electrical impulse spreads through the heart, some electrical current spreads through the surrounding tissue to the skin. electrodes placed on opposite sides of the heart can measure the electrical potential generated by the current. The normal ECG consists of P waves, a QRS complex (often made up of 3 waves; Q, R and S) and a T wave

Watch for the appearance of extra systoles - beats induced by the electrical stimulus (Figure 3). Your objective is to determine when, during the cycle, the heart is refractory (i.e. when the electrical stimulus does not result in an extra contraction). Labelled chart records (or copies of them) of this experiment will be included in your lab ...

Electrical Event. A. electrical events caused by conducting system are recorded as deflection waves transmitted to entire body by means of electrolytes. The recording of heart electrical waves is called an ECG or EKG - electrocardiogram. B. ECG has 3 kinds of deflection waves. 1. P wave . a. atrial depolarization (electricity) 2. QRS complex. a.
