Wolff-Parkinson-White Syndrome
The syndrome is characterized by a short PR interval and a long QRS interval with a delta wave.[fpnotebook.com]
Note the short PR interval .[en.wikipedia.org]
ECG Presentation • Short PR interval • Slurred initial upstroke of QRS – delta wave • Relatively normal , narrow terminal QRS –main QRS deflection • Slight widening of QRS[slideshare.net]

The syndrome described by Lown, Ganong, and Levine in 1952 associated the occurrence of tachycardia with presence of a short PR interval and normal QRS.[emedicine.medscape.com]

Preexcitation Syndrome
PR interval (usually 0.1 second or less; occasionally normal) together with a prolonged QRS complex with a slurred initial component (delta wave).[medical-dictionary.thefreedictionary.com]
Short PR interval . Normal QRS complex. Norma T wave.[en.my-ekg.com]
The combination of a short PR interval and an abnormally long QRS complex comprises the ECG diagnosis of ventricular pre-excitation.[frca.co.uk]

Cushing's Disease
Cushing's disease is caused by prolonged exposure to inappropriately high levels of the hormone cortisol due to increased secretion of adrenocorticotropic hormone. Common symptoms include weight gain, skin changes, hyperhidrosis, infertility, hirsutism, amenorrhea, muscle weakness and psychological problems. The[…][symptoma.com]

Myocardial Infarction
History The patient’s history is critical in diagnosing myocardial infarction (MI) and sometimes may provide the only clues that lead to the diagnosis in the initial phases of the patient presentation. Patients with typical acute MI usually present with chest pain and may have prodromal symptoms of fatigue, chest[…][emedicine.medscape.com]
