心律失常的常见检查
Several tests can help your doctor diagnose an 心律失常 and monitor the effectiveness of your treatment.
动态心电监测
You can think of a 动态心电监测 (or continuous ambulatory electrocardiographic monitor) as a small, 可移植的 心电图(EKG) 录音机.
霍尔特监视器 can record 24 hours or more of continuous electrocardiographic signals. This gives doctors a “movie” of the heart’s electrical activity, as opposed to the much shorter glimpse provided by an EKG.
Your doctor may ask you to keep a diary of your activities and symptoms. 晚些时候, the 动态心电监测 results can be compared to your daily log to see how your activities or symptoms correspond to your measured heart rhythm.

For suspected 心律失常s that occur infrequently or pass quickly, your health care professional might suggest that you wear a cardiac event 录音机.
Various kinds of event monitors attach with bracelets, finger clips or patches worn under the arms for a month or two. The data about your heart’s electrical system are recorded and stored. You can then transmit the results to your doctor to be analyzed.

压力测试或运动压力测试
A 压力测试 or an exercise 压力测试 can help diagnose people whose suspected 心律失常s are caused by exercise.
在运动压力测试中, you walk or run on a treadmill or ride a stationary bicycle while your heart rate and rhythm are monitored. This can cause an 心律失常, allowing your health care professional to study the abnormal heartbeat.

倾斜台测试
A tilt-table test may be suggested if you’ve suffered fainting spells. It reveals how your heart rate and blood pressure respond when changing positions from lying down to standing up.
在这个测试中, a catheter may be placed in an artery to monitor blood pressure from within the blood vessel. An intravenous line (a small plastic tube in a vein) may also be started before the test.
If the cause of the fainting spells is not initially discovered, medications can be supplied through the intravenous line or by mouth to help produce the episodes.

电生理学的测试
电生理学的测试, also called an EP study, can reveal suspected 心律失常s.
在这个过程中, 在局部麻醉下进行, temporary electrode catheters are threaded through peripheral veins (or arteries) into the heart using a fluoroscope. These electrode catheters are positioned in the atria, ventricles or both. They record the heart’s electrical signals and “map” the path of electrical impulses during each heartbeat.
This test can cause known but infrequent 心律失常s, allowing them to be diagnosed. It can help trigger hidden tachycardia (fast heart rate) or bradycardia (slow heart rate).
食管电生理检查
在这个过程中, 一个瘦, flexible catheter is inserted into your nostril and positioned in the esophagus (the tube that connects the mouth and stomach). The catheter’s lead performs an electrocardiogram (EKG). The catheter’s proximity to the heart allows for more accurate results than a conventional EKG.
This procedure can cause unpredictable 心律失常s for diagnosis. Medications can be administered as part of the test to determine the most effective approach.
超声心动图
An echocardiogram is a painless procedure that uses ultrasound waves to reveal your heart’s size, 结构和运动. This type of 超声心动图 uses sound waves in much the same way that an ultrasound test uses sound waves to monitor a baby’s growth in the womb.
An echocardiogram often provides valuable information about a heart with an 心律失常. The most common type of echocardiogram is transthoracic 超声心动图 (TTE).
