The cause of sinus tachycardia can usually be discovered simply by assessing the patient. For example, a sudden fright causes release of adrenaline, and the sinus node responds by speeding up. Sinus tachycardia is usually a normal physiologic reaction to the body’s need for increased cardiac output. Sinus tachycardiaĪ sinus rhythm faster than 100 bpm is called sinus tachycardia. Here are some common abnormal rhythms and what they might mean. Some slight variations in ECG rhythms are normal others require closer attention, and possible intervention. 12-lead machines offer perhaps the most detail, with information recorded in 10-second intervals. Continuously worn event monitors, such as Holter monitorsĪlthough designed for continuous use, there are some limitations to the information these monitors can provide.Combination monitor, 12-lead, pacemaker, and defibrillator (usually portable).While there are many variations, these are some of the main types of ECG machines: Related: Basic ECG Recognition and Interpretation Types of ECG machines Nurses caring for monitored patients should understand how to read and interpret ECG rhythm strips, as well as be able to identify ECG patterns that warrant immediate interventions. ECG rhythm recognition and interpretation is an essential skill for nurses practicing in areas where patients are cardiac-monitored. The continual beep-beep-beep of ECG machines forms the auditory backdrop of many healthcare environments.
