Question
1) What is the normal measurement of the following and what is happening in the heart:...
Answers
Ans.
1. a) P wave: 80 milliseconds
b) QRS complex: 80-100 milliseconds
c) QT interval: 420 milliseconds or less if heart rate is 60 beats per minute (bpm)
2. According to AHA (American Heart Association)
a) white = Right arm RA
b) black = Left arm LA
c) green= Right leg RL
d) red = Left leg LL
e) brown = left midaxillary / center of chest.
3. Arrhythmia--
Improper beating of the heart, whether irregular, too fast or too slow.
Cardiac arrhythmia occurs when electrical impulses in the heart don't work properly.
Characteristics of rhythm-
Noticeable arrhythmia symptoms may include: A fluttering in your chest. A racing heartbeat (tachycardia) A slow heartbeat (bradycardia).
- A fluttering in your chest
- A racing heartbeat (tachycardia)
- A slow heartbeat (bradycardia)
- Chest pain
- Shortness of breath
- Anxiety
- Fatigue
- Lightheadedness or dizziness
- Sweating
- Fainting (syncope) or near fainting

Atrial flutter and atrial fibrillation are both abnormal heart rhythms. ... In atrial fibrillation, the atria beat irregularly. In atrial flutter, the atria beat regularly, but faster than usual and more often than the ventricles, so you may have four atrial beats to every one ventricular beat.
Atrial flutter is a type of atrial tachycardia that results in an arrhythmia (rhythm disorder or not a normal rhythm) where the atria of the heart beat too quickly in a fast, usually regular, rhythm.
Atrial fibrillation is another type of atrial tachycardia that is closely related to atrial flutter. However, the arrhythmia that occurs in AFib is much more chaotic and results in a fast and usually very irregular heart rhythm or a atypical and irregular ventricular rate that can effect heart health.
5.
Heart arrhythmia, also known as irregular heartbeat or cardiac dysrhythmia, is a group of conditions where the heartbeat is irregular, too slow, or too fast. Arrhythmias are broken down into: Slow heartbeat: bradycardia. Fast heartbeat: tachycardia. Irregular heartbeat: flutter or fibrillation.
Treatment-
Treatment varies- if required, treatment includes anti-arrhythmic drugs, medical procedures, implantable devices and surgery.
Medications - Antiarrhythmic, Calcium channel blocker, Beta blocker and Dietary supplement
Medical procedure-. Cardioversion and Radiofrequency ablation
Devices-. Pacemaker and Implantable cardioverter defibrillator
Supportive care-. Cardiac monitoring
