| MP term: | prolonged QRS complex duration |
| Synonym: | prolonged QRS duration |
| Synonym: | prolonged QRS interval |
| Synonym: | QRS interval elongation |
| Synonym: | widened QRS complex |
| MP id: | MP:0010392 |
| Definition: | increase in the length of time of the largest-amplitude portion of the ECG, caused by currents generated when the ventricles depolarize prior to their contraction; prolongation of the QRS complex duration reflects slowed conduction in the heart |
| Number of paths to term: | 2 |
