Households with lawns or gardens must factor in the amount of water sprinkled on grass, flowers and vegetables. Outdoor watering uses 5 to 10 gallons per minute. So in 10 or 20 minutes, you may use 100 gallons â the amount industry experts estimate is used by an average person each day for all personal water needs!
Cardiac conduction is the driving force behind the cardiac cycle. This cycle is the sequence of events that occur when the heart beats. During the diastole phase of the cardiac cycle, the atria and ventricles are relaxed and blood flows into the atria and ventricles. In the systole phase, the ventricles contract sending blood to the rest of the body.
INTRODUCTION. Electrical cardioversion and defibrillation have become routine procedures in the management of patients with cardiac arrhythmias. Cardioversion is the delivery of energy that is synchronized to the QRS complex, while defibrillation is asynchronous delivery of a shock randomly during the cardiac cycle. Early defibrillators delivered energy in a monophasic waveform, meaning that electrons flowed in a single direction.
