bradycardia and tachycardia
Always. If you witnessed the collapse, immediate application of the AED offers the best chance of successful defibrillation. If the patient does not need defibrillation (only two heart rhythms are shocked by an AED), the AED won't attempt it, so applying one can't hurt, and it may save a life. Hook up the AED when the absence of a pulse is confirmed.
From the AHA related link: Many sudden cardiac arrest victims are in ventricular fibrillation (VF). VF is an abnormal, chaotic heart rhythm that prevents the heart from pumping blood. You must defibrillate a victim immediately to stop VF and allow a normal heart rhythm to resume. The sooner you provide defibrillation with the AED, the better the victim's chances of survival. Several studies have documented the effects of time to defibrillation and the effects of bystander CPR on survival from SCA. For every minute that passes between collapse and defibrillation, survival rates from witnessed VF SCA decrease 7 to 10 percent if no CPR is provided. When bystander CPR is provided, the decrease in survival rates is more gradual and averages 3 to 4 percent per minute from collapse to defibrillation. CPR can double or triple survival from witnessed SCA at most intervals to defibrillation.
It is where two or more different rhythms are going on at the same time.Polyrhythm is when two rhythms or melodies are played at once and contrast/match together.
polyrythm
The two rhythms an AED will only shock are Ventricular Fibrillation (V-Fib) and Ventricular Tachycardia (V-Tach).
Migration is a recurring pattern of movement between two or more locations. This occurs in response to environmental rhythms or seasonal changes.
Subdivide the beat by two.

treatment of amblyopia may include by covering stronger eyee and using glasses
yin and yang
the surgeon may insert a pack of gauze into the nose to stop the blood flow for subsequent removal after a day or two.
infections are usually treated with two antibiotics at once. Pseudomonas infections may be treated with combinations of ceftazidime (Ceftaz, Fortraz, Tazicef), ciprofloxacin (Cipro).
