Webb12 feb. 2010 · A slower-than-normal rate of impulses in the sinus node is medically referred to as sinus bradycardia (SB). Also called the sinoatrial node (SAN), the sinus node initiates the electrical impulses within the heart, triggering the heart to beat or contract. Webb17 maj 2024 · In junctional rhythm, the atrioventricular junction becomes the default pacemaker and the resulting heart rate is then called a junctional rhythm, not a sinus rhythm. There is no difference to how these two areas function – they are both composed of pacemaker cells – but the target cells differ and this is an important difference.

WebbChemical cardioversion can help to treat a number of different abnormal heart rhythms. It's sometimes used to treat atrial fibrillation (AFib).

WebbArrhythmias. An arrhythmia (ah-RITH-me-ah) is a problem with the rate or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia (TAK-ih-KAR-de-ah). A heartbeat that is too slow is called bradycardia (bray-de-KAR-de-ah). WebbThese include atrial fibrillation, atrial flutter, atrial tachycardia. A period of fast heart rates is often followed by very slow heart rates. When there are periods of both slow and fast heart rates (rhythms) the condition often will be called tachy-brady syndrome. Some medicines can make abnormal heart rhythms worse, especially when doses ... WebbSeconds and minutes count when cardiac arrest occurs. The likelihood of survival decreases for every minute that goes by without this type of help. Is an AED useful for all types of cardiac arrest? No. Other abnormal rhythms like a very slow heart rate or no electrical rhythm at all, can't be treated with an AED. rcw property acquisition
