107 Possible Causes for Lateral Q Wave

  • Hypertrophic Cardiomyopathy

    Lateral Q waves are more common than inferior Q waves in HCM.[lifeinthefastlane.com] wave in the anterior precordial and lateral limb leads, short P-R interval with QRS suggestive of preexcitation, atrial fibrillation (poor prognostic sign), and a P-wave abnormality[emedicine.medscape.com] Deep narrow Q waves 40 ms wide in the lateral leads I, aVL and V5-6.[lifeinthefastlane.com]

  • Myocardial Infarction

    Typical picture of changes ST elevation – then later, T inversion – , then later, Q wave appears Other patterns of ECG change: ST- depression Reciprocal change – sometimes[almostadoctor.co.uk] Example 5 Prior Anteroseptal / Lateral MI Deep Q waves in V1-3 with markedly reduced R wave height in V4.[lifeinthefastlane.com] In fact, a prominent R wave in V 1 was shown to be due to lateral, not posterior, MI. 2 This case shows an isolated lateral MI because no Q waves were displayed in the inferior[circ.ahajournals.org]

  • Pericardial Cyst

    The electrocardiogram revealed pathological Q waves in lateral limb leads with T wave inversions in lateral limb and chest leads.[keralamedicaljournal.com]

  • Acute Myocardial Infarction

    Example 5 Prior Anteroseptal / Lateral MI Deep Q waves in V1-3 with markedly reduced R wave height in V4.[lifeinthefastlane.com] How to Recognise Anterior STEMI ST segment elevation with Q wave formation in the precordial leads (V1-6) the high lateral leads (I and aVL).[lifeinthefastlane.com] Poor R wave progression (R wave height 3mm in V3). Abnormal Q waves and T-wave inversion in I and aVL.[lifeinthefastlane.com]

  • Myocardial Contusion

    An electrocardiogram performed in the coronary care unit revealed Q waves at the lateral leads and repolarization anomalies inferolaterally.[revespcardiol.org]

  • Tricyclic Antidepressant Overdose

    Causes of Rightward Axis Deviation – Lead misplacement, Hyperkalemia (can do anything on the ECG) Ventricular ectopy (VT), Lateral MI (Q-waves in lead I), Left posterior fascicular[foamcast.org]

  • Thrombolytic Therapy

    Among patients who arrived late, 63% (35 of 56) had Q wave infarction and 84% (47 of 56) had symptoms typical of acute MI. Mortality was 29% (16 of 56) in this group.[care.diabetesjournals.org] Of diabetic patients who were not thrombolyzed, 60% (48 of 80) arrived at the hospital later than 12 h after onset of symptoms.[care.diabetesjournals.org]

  • Left Ventricular Aneurysm

    Later, ECHOcardiography showed a large inferior LVA. Leads II, III and aVF show Q waves, minimal ST elevation, negative T waves and fragmented QRS. ECG 3.[metealpaslan.com]
