A QRS duration of greater than 0.12 seconds is considered abnormal.Prolonged electrocardiographic QRS duration is frequently observed in congestive heart failure (CHF) patients.
EKG Mean Axis and Supraventricular Rhythm Review
EKG RHYTHM TUTORIAL - coldbaconPR interval: progressively longer until a P wave is not conducted and the QRS complex dropped, then the cycle repeats PR interval: progressively longer until a P wave is not conducted and the QRS complex dropped, then the cycle repeats.QT interval with duration of QRS complex in the presence of a wide QRS complex, whereas JT interval only moderately correlated with prolonged QRS duration.

The PR interval is the time in seconds from the beginning of the P wave to the beginning of the QRS complex.QRS 80-120ms: Measure from the onset to the end of the QRS interval.QRS complexes may be normal or wide and bizarre if BBB is present.Afterward all measurements gradually returned to the resting level.
Abnormal EKG’s and Corresponding Arterial WaveformsIt is also used to detect myocardial injury, ischemia, and the presence of prior infarction.Started in 1995, this collection now contains 6578 interlinked topic pages divided into a tree of 31 specialty books and 721 chapters.The PR, QRS, and QT are intervals (a portion of the baseline and at least one wave) that are measured in seconds on an ECG.

The waveform may well corss the isolelectric line several times before the end of the QRS interval.QT interval is measured from the onset of QRS to the end of T wave.The time intervals between consecutive heart beats are customarily measured in the electrocardiogram from the beginning of a QRS complex to the beginning of the next QRS complex, so these intervals might be called QQ intervals, but they are conventionally named RR intervals.
QT interval - WikipediaFPnotebook.com is a rapid access, point-of-care medical reference for primary care and emergency clinicians.The heart rate-corrected QT interval (QTc) is the traditional measurement for assessing the duration of ventricular repolarization.
Supraventricular Tachycardia (SVT) - Learning CentralB: During overdrive pacing from the right atrium, narrow QRS complex and normal AH and HV intervals were noted.Sodium channel blockers including class I antiarrhythmics by blocking inward sodium current can slow depolarization, reduce conduction velocity, and prolong the QRS interval and consequently may.Mechanisms which...
