Tachycardia, also called tachyarrhythmia, is a heart rate that exceeds the normal resting rate. [1] ... but if VT persists it is extremely dangerous, ...
Sinus tachycardia is a sinus rhythm of the heart, with an increased rate of electrical discharge from the sinoatrial node, resulting in a tachycardia, a heart rate that is higher than the upper limit of normal (90-100 beats per minute for adult humans).
Nicardipine, Nifedipine, and Isradipine are calcium channel blockers that work to decrease systemic vascular resistance and subsequently lower blood pressure. Hydralazine and Sodium nitroprusside are systemic vasodilators, thereby reducing afterload, however can be found to have reflex tachycardia, making them likely second or third line choices.
Fall prevention is critical, particularly in older adults, Dr. Kathryn Boling, a primary care physician at Baltimore's Mercy Medical Center, tells Yahoo Life. “It’s important to get things out ...
Tachycardia is a resting heart rate more than 100 beats per minute. This number can vary as smaller people and children have faster heart rates than average adults. Physiological conditions where tachycardia occurs: Pregnancy; Emotional conditions such as anxiety or stress. Exercise
Tachycardia may result in palpitation; however, tachycardia is not necessarily an arrhythmia. Increased heart rate is a normal response to physical exercise or emotional stress. This is mediated by the sympathetic nervous system on the sinus node and called sinus tachycardia.
Multifocal atrial tachycardia is characterized by an electrocardiogram (ECG) strip with three or more discrete P wave morphologies in the same lead, not including that originating from the sinoatrial node, plus tachycardia, which is a heart rate exceeding 100 beats per minute (although some suggest using a threshold of 90 beats per minute ...
Tachycardia, a fast heart rate, is typically the first abnormal vital sign. [3] When resulting from blood loss, trauma is the most common root cause, but severe blood loss can also happen in various body systems without clear traumatic injury. [3]
