Conditions We Treat

Arrhythmias that cause tachycardia – an abnormally fast heart rate – may include:

• Atrial Fibrillation
• Atrial Flutter                                                     
• Ectopic Atrial Tachycardia
• Junctional Ectopic Tachycardia
• Permanent Junctional Reciprocating Tachycardia          
• Supraventricular Tachycardia (SVT)              
• Torsades de Pointes                                       
• Ventricular Fibrillation
• Ventricular Tachycardia
• Wolff-Parkinson-White Syndrome (WPW)      

Arrhythmias that lead to bradycardia – a slower than normal heart rate – include:

• Cardiac Infiltrative Diseases
• Congenital Heart Block                                   
• Diffuse Conduction System Disease              
• Frequent Atrial Premature Beats
• Sick Sinus Syndrome
• Surgical Heart Block

Each type of arrhythmia requires a unique, individualized approach for successful diagnosis and management.

Some disorders have no symptoms but can be discovered during a routine exam. Certain types of arrhythmia, if left undiagnosed and treated, can lead to serious symptoms including heart enlargement and heart failure.

Inherited Arrhythmias

Cardiac channel abnormalities (channelopathies) are a heart disease that can disrupt the timing of the heartbeat, leading to serious and potentially life-threatening arrhythmias. They usually have a genetic origin. If one family member has this condition, it means that several family members are likely to be affected. 

At the Phoenix Children’s Heart Center, we treat these and other channelopathies: 

• Long QT Syndromes
• Brugada Syndrome
• Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT)          
• Short QT Syndromes                                                                      
• Progressive Cardiac Conduction Disease

If there is a chance of an inherited arrhythmia in your family, it is vital that all members of your family – and often extended family – are also screened for this condition. 

Tailored Care for the Family

Managing inherited arrhythmias requires advanced expertise and experience – especially since overtreatment or undertreatment can have serious effects.

At the Phoenix Children’s Heart Center, our specialty-trained cardiologists have specific expertise in the diagnosis and management of all types of inherited arrhythmias. We offer comprehensive and customized care for every family member, from the youngest to the oldest.
