The nurse suspects an old infraction for a patient presents with chest pain. the nurse performs a12-lead electrocardiogram that reveals an abnormal q wave.
An old infract means that the patient possibly had a heart attack at an undetermined time in the past. A second test is typically taken to confirm the finding, because the results may instead be due to incorrect placement of electrodes on the chest during the exam.
Old infractions are found on electrocardiogram through loss of anterior forces, leaving Q waves in leads V1 and V2. This is a cause of poor R wave progression.
Causes of old myocardial infarction are smoking, high blood pressure, diabetes, old age.

Abnormal psychology is the study of unusual behavior,thoughts, and emotions.
Hypertension is high blood pressure, cardio-respiratory fitness is the process of the circulatory and respiratory system use to supply oxygen to the body so the body could sustain during physical activity. Based on my research because of how much blood the heart pumps it could caused high blood pressure because the blood rises up against your artery walls which could cause long term diseases. Now when your doing physical exercise your heart will pump blood faster because that's how you get the oxygen throughout your body. To sum up, "cardio-respiratory exercise can cause hypertension (high blood pressure) because when your doing exercise it will increase your heart rate and the blood could be pushed against your artery walls and cause hypertension."
Hope this helps!
I’m sorry but is this a language?
Answer: to digest food and to kill microbes
Food that we eat is mostly not sterile and contain some microbes. A strong acid can destroy the microbes and prevent infection in the gastrointestinal system. Acid also can help destroying food, make it much smaller. A Smaller piece of food is easier to digest since the area that able to do chemical reaction will be bigger.
