title: Presence of a critical stenosis in left anterior descending coronary artery alongside a short "P-R" and "Q-T" pattern, in the same electrocardiographic record.
abstract: The knowledge of the heart and its functions is increasing every day. However, many cardiac dysfunctions remain undocumented. One of them might be the presence of the Wellens' sign, minimally elevated or isoelectric ST segments, and inverted T waves in the precordial leads, without changes in the QRS complex, together with a shortened of "P-R and Q-T intervals" in the same electrocardiographic record. Both patterns are greatly underdiagnosed. The key to an accurate diagnosis of both dysfunctions must begin with a detailed analysis of all the symptoms reported by the patient. The ECG recording provides an almost definitive confirmation: The T-wave characteristics in precordial derivations. The duration of P-R and Q-T intervals.
