Because the QT interval shortens as the heart beats faster and lengthens as it slows, a raw QT value cannot be interpreted on its own. Correction formulas, the most common being Bazett's formula published in 1920, adjust the measured QT to a standardized heart rate of 60 bpm, producing the corrected QT interval (QTc).<\/p>\n<p>The QTc is a key screening measure for the risk of ventricular arrhythmias, particularly <em>Torsades de Pointes<\/em>, a polymorphic ventricular tachycardia that can degenerate into ventricular fibrillation and sudden cardiac death. QTc prolongation may be congenital (long QT syndrome) or acquired \u2014 most often caused by medications such as certain antiarrhythmics, antibiotics, antipsychotics, and antiemetics, or by electrolyte disturbances like hypokalemia and hypomagnesemia.<\/p>\n<p>General interpretation thresholds for Bazett-corrected QTc in adults: values below 440 ms in men and 460 ms in women are considered normal; values of 500 ms or more in either sex indicate pronounced prolongation with a substantially elevated arrhythmia risk and usually warrant urgent clinical attention. Very short QTc values (below about 340 ms) are also abnormal and may suggest short QT syndrome. Interpretation should always account for the patient's sex, age, medications, and the clinical context.<\/p>\n<p>For context in broader cardiovascular assessment, you may also find our <a href=\"https:\/\/wpcalc.com\/en\/medical\/cha2ds2-vasc-score\/\">CHA\u2082DS\u2082-VASc score calculator<\/a>, <a href=\"https:\/\/wpcalc.com\/en\/medical\/mean-arterial-pressure\/\">mean arterial pressure calculator<\/a>, and <a href=\"https:\/\/wpcalc.com\/en\/medical\/target-pulse-rate\/\">target heart rate calculator<\/a> useful.<\/p>\n<h2>Assumptions, Limitations and Practical Tips<\/h2>\n<ul>\n<li><strong>Bazett's limitations:<\/strong> the formula overcorrects (gives falsely long QTc) at heart rates above about 90\u2013100 bpm and undercorrects at rates below about 60 bpm. At extreme heart rates, alternative corrections such as Fridericia (QT divided by the cube root of RR) or Framingham are more accurate.<\/li>\n<li><strong>Measurement quality matters:<\/strong> the end of the T wave can be difficult to identify, especially with biphasic T waves, U waves, or artifact. If the T wave merges with a U wave, measure to the nadir between them and note this in the record.<\/li>\n<li><strong>Which beats to use:<\/strong> in atrial fibrillation the RR intervals vary beat to beat; average the QT and RR over several (usually 3\u20135) consecutive beats.<\/li>\n<li><strong>Units:<\/strong> keep units consistent. This calculator converts milliseconds, seconds, and millimeters (at standard 25 mm\/s paper speed) to seconds automatically; if you enter heart rate, the RR interval is derived as \\(60\/HR\\) in seconds.<\/li>\n<li><strong>Clinical judgment:<\/strong> a single QTc value is a screening tool, not a diagnosis. Borderline or ambiguous results, especially in patients on QT-prolonging drugs, should be reviewed by a clinician and confirmed with a formal 12-lead ECG.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the corrected QT interval (QTc) using Bazett's formula.
