Ventricular Tachycardia
Common causes of ventricular tachycardia include ischemic heart disease, illicit drugs (cocaine and methamphetamine), structural heart disease (including congenital heart diseases such as tetralogy of Fallot), inherited channelopathies, drug toxicity (digoxin, drugs that prolong the QT interval) and electrolyte disturbances (such as hypokalemia, hypomagnesemia, and hypocalcemia).

Bloodstream infections caused by endogenous flora and reactivation of latent infections account for a majority of initial febrile episode in neutropenic patients with cancer. Common bacterial isolates that cause bacteremia in the setting of neutropenia are listed in Table 1.[1] Certain endogenous microorganisms may be reactivated and exit latency during immunosuppression. These include herpes simplex virus, varicella-zoster virus, Epstein-Barr virus, cytomegalovirus, hepatitis B and C viruses, and Mycobacterium tuberculosis. Exogenous pathogens carried by contaminated blood products, medical equipment and devices, water sources, and health care workers represent less common sources of infection. These include Clostridium difficile, respiratory syncytial virus, vancomycin-resistant enterococci, and other multidrug resistant bacteria.[2]
Fungal infections often take place in the setting of prolonged or profound neutropenia after administration of empirical therapy. Candidiasis may range in severity from mucosal or cutaneous infection to septicemia, endocarditis, or disseminated infection. Aspergillus, on the contrary, typically causes life-threatening infection of the sinuses and lungs, particularly after protracted neutropenia.[3]
