While your heart may be beating faster than at rest in sinus tachycardia, it is not interfering with other electrical impulses in the heart. 1 Atrial or supraventricular tachycardia (SVT) An abnormally fast heart rate that begins in the upper chambers of the heart is called atrial or ...

An arRHYTHMmia (see the word “rhythm” in there?), on the other hand, is not steady and may cause your heart to speed up or slow down. For persons with Sick Sinus Syndrome, the arrhythmia takes the heart someplace else entirely – someplace too fast (tachycardia), too slow (...
An arrhythmia is a problem with the rate or rhythm of the heartbeat. It may involve the heart beating too fast, too slow or with another form of irregularity. When the heart beats too fast, it is called tachycardia. A slow heartbeat is called bradycardia. ...
(g) Second-degree AVB; (h) ventricular extrasystoles; (i) ventricular tachycardia. (j) Relative percentages of SAN or AVN dysfunctions preceding a period of ventricular tachycardia in n ¼ 5 mutant mice (SP, sinus pauses; ESV, ventricular extrasystoles). (k) ECG recorded from Mut/GIRK4...
They also reported other adverse events such as sinus tachycardia, hypertension/hypotension not requiring intervention, chest pain without objective evidence of cardiac ischemia, and local tissue ischemia. Sixty-seven patients were noted to have at least one adverse event with an adverse event rate ...
Proarrhythmia is a condition in which a person experiences an irregular heart beat that is caused by or aggravated by drugs...
Common side effects from systemic absorption of cocaine include high blood pressure (hypertension), rapid heart rate (tachycardia), sinus tachycardia, slow heart rate (bradycardia), ECG abnormalities, irregular heart rhythm (arrhythmia), and others. Cocaine is a highly addictive substance, and misuse...
Can you detect any signs guiding you to the correct diagnosis of the device-related problem and themost likely type of arrhythmia? The tracing derived from the dual-chamber ICD in Figure 1A shows a regular tachycardia with a CL of 324 ms detected in the VT-2 zone (181-221 beats per...
