¿Cómo se ve un electrocardiograma anormal?

- An electrocardiogram records the electrical signals in your heart
- A prescription or a recommendation to someone or something like pills or a specialist in some field.
- The V stands for Vector and R, L and F stand for Right, Left and Foot.
- 12 leads which are derived by means of 10 electrodes.
- Step 1 – Heart rate.
Step 2 – Heart rhythm.
Step 4 – P waves.
Step 5 – PR interval.
Step 6 – QRS complex.
Step 7 – ST segment.
Step 8 – T waves.
- Place RA (white) electrode under right clavicle, mid-clavicular line within the rib cage frame. Place LA (black) electrode under left clavicle, mid-clavicular line within the rib cage frame. Place LL (red) electrode on the lower left abdomen within the rib cage frame. Select the ECG Lead II at the bedside monitor.
- An ECG can help your doctor identify an unusually fast heart rate (tachycardia) or an unusually slow heart rate (bradycardia). Heart rhythm. An ECG can show heart rhythm irregularities (arrhythmias). These conditions may occur when any part of the heart's electrical system malfunctions.

- QRS complex is between 0.08 and 0.10 seconds & A QRS duration of greater than 0.12 seconds is considered abnormal.

- Shortness of breath, tightness in the chest, an abnormally fast heartbeat, sudden weakness, or feeling like you are going to pass out are common signs of problems that would show an abnormal ECG.

They need to know because sometimes they have a symptom

Muscles in the body us with a lot of things for example, if i wanted to lift a heavy box and had no muscle i would just collapse where i was because of the fact muscles hold us together. overall they are 650 muscle in the human body, all of them have different purposes and ways to keep us together. there are three types of muscle in the body skeletal, smooth, and cardiac muscle. skeletal muscle are attached to the bone and with movement. smooth muscle, this is found in the wall of our organs, such as our stomach, this muscle with movement   as well, without this muscle, we would only be allowed to eat small amounts. the cardiac muscle is the heart muscle and probably the most important one. these are only found in the walls of the heart and the heart pump blood to the other parts of your body. we have two different types of muscle fibers, slow twitch and fast twitch. slow twitch muscles enable long-endurance feats such as distance running. fast twitch fatigue faster but are used in powerful bursts of movements like sprinting. there are three different types of muscle contractions concentric, eccentric, isometric. concentric contraction causes muscles to shorten, thereby generating force.   eccentric contractions cause muscles to elongate in response to a greater opposing force. isometric contractions generate force without changing the length of the muscle.: //athleticquickness.com/muscle-contraction-types-part-1/
