Find out what this side can share about learning ECG
Electrocardiography is the most commonly used test for evaluating cardiac status, graphically records the electrical current (electrical potential) generated by the heart. This current radiates from the heart in all directions and, on reaching the skin, is measured by electrodes connected to an amplier and strip chart recorder. The standard resting ECG uses five electrodes to measure the electrical potential from 12 different leads; the standard limb leads (I,II,III), the augmented limb leads (aVf, aVL, and aVr), and the precordial, or chest, leads (V1 through V6).

Period of Intuitive Nursing/Medieval Period
- Nursing was “untaught” and instinctive. It was performed of compassion for others, out of the wish to help others.
- Nursing was a function that belonged to women. It was viewed as a natural nurturing job for women. She is expected to take good care of the children, the sick and the aged.
- No caregiving training is evident. It was based on experience and observation.
- Primitive men believed that illness was caused by the invasion of the victim’s body of evil spirits. They believed that the medicine man, Shaman or witch doctor had the power to heal by using white magic, hypnosis, charms, dances, incantation, purgatives, massage, fire, water and herbs as a mean of driving illness from the victim.
- Trephining – drilling a hole in the skull with a rock or stone without anesthesia was a last resort to drive evil spirits from the body of the afflicted.
Nerve cells arranged in networks communicate information with one another through neurotransmission which is the conduction of electrical messages from neuron to neuron. The electrochemical messages cross the synapses between neural cells by way of special chemical messengers called neurotransmitters. (more…)
