Answer:
a. Absent p wave is present in atrial fibrillation.
b. Abnormally long QRS complex is present in right or left bundle branch block.
c. Abnormally long PR interval is present in first degree heart block.
d. extra QRS complexes are present in abnormal pacemaker or abnormal conducted beat.
Explanation:
By reading the ECGS we can fine a number of abnormalities by simply locating problems in P, QRS, T waves, PR intervals and ST segments.
Absent P wave in an ECG represents Atrial fibrillation or sinoatrial arrest. Atrial fibrillation is an abnormal heart rhythm also know as arrhythmia characterized by rapid and irregular beating of the atrial chambers of the heart.
Abnormally long QRS complex represents Right or left bundle branch block, hyperkalemia, drug induced or abnormal ventricular rhythm.
Abnormally long PR interval represents heart block. The PR interval reflects impulse conduction from the atria to the ventricles is normal. A long PR interval indicates a slowing of conduction between the atria and ventricles, usually due to slow conduction through the atrioventricular node (AV node). This is known as first degree heart block.
Extra QRS complexes represents abnormal pacemaker conductivity.
The answer to the above question is that 0.3 ml that is the syringe about one-third full of epinephrine will be administered to the patient.
<h3>What is
epinephrine?</h3>
In an emergency, this medication is used to treat extremely serious allergic reactions to foods, medicines, or other substances. Epinephrine works swiftly to enhance breathing, speed up the heart, boost blood pressure, stop hives, and lessen facial, lip, and neck swelling.
According to your doctor's instructions, inject this drug into your thigh.
After administering epinephrine, seek immediate medical attention. Inform the medical practitioner that you administered an epinephrine shot to yourself. If your symptoms do not improve or if they come back after one dose of epinephrine, you might need another dose.
