Welcome to our Tachycardia Reference Page. This page provides a summary definition followed by introductions to our practice drills, quizzes, lessons and interactive guides.
Tachycardia is a rapid, above normal, heart rate when the subject is at rest. A resting heart rate that exceeds one hundred beats per minute can be classified as tachycardia.
Tachycardias can be classified by their origin (atria or ventricles).
Ventricular tachycardia originates in the ventricles and includes the follow abnormalities:
Supraventricular tachycardias originate above the ventricles. They include:
Several types of tests may be employed to diagnose tachycardia: electrocardiograms,
holter monitors, event monitors, stress tests, echocardiograms, electrophysiology studies, head-up-tilt-table tests and cardiac catheterization. On this website you will find provide tools for heart sounds and electrocardiograms.
If you wish to practice taking pulse rate, use our blood pressure case studies.
Using the play button on the torso, you can listen to tachycardia. For more
information, lessons and quizzes for heart sounds, visit our page:
EKG tracings also can reveal tachycardia. The rhythm strip below show several types of tachycardia:
A good starting point for learning EKG interpretation is our EKG Basics training course. The course provides training on the key features of an EKG tracing. These features include observing P-wave forms, measurement of EKG intervals and segments, assessment of rhythm, calculating heart rate, and the evaluation of other relevant wave segments. The arrhythmia practice drills allow students to build skills interactively.
The heart arrhythmia practice drills provide a test EKG tracing and users are asked to identify the type of arrhythmia. Many of these drills include tachycardia EKG tracings. Each answer is immediately evaluated and the correct classification of the EKG tracing is provided, along with a detailed explanation. A directory of arrhythmias is also provided.
The quiz is structured like a classroom exam. The quiz present twenty EKGs. Users answer each question and at the end of the quiz, a fully graded report is provided. This graded report provides scoring as well as the correct answer to each question. Top scores and mean scores are also provided. This quiz draws its questions from a library of over 300 EKGs, allowing users to take the quiz multiple times.
Try the beta version of our ECG monitor challenge. This quiz uses a simulated patient monitor with moving waveform instead of a paper tracing. As with the quiz described above, twenty questions are presented, then a graded report is available.
