Is a heart block a one time thing or a chronic disorder in the heart?

"Depends" Heart blocks are very variable from fairly benign (first degree) to pretty serious (complete heart block). They can be transient and benign like mobitz type 1 or they can be permanent. Some heart blocks may be more serious but can be reversed if their is an underlying problem such as lyme disease or medication reaction. Often times however a pacemaker may need to be implanted.

Is a heart block a chronic disorder in the heart?

Arrhythmia. Heart block leading to a slowed heart rate can be acute, occurring secondary to external circumstances like increased vagal stimulation, low oxygen levels, or threatened coronary circulation. It can also be chronic occurring as a result of conduction system disease in patients with sleep apnea, myocardial scarring, aging, or infiltrative deposits. Read more...

If someone had complete heart block would their heart rate be slow all the time?

Complete av block. Complete av block means the p waves aren't conducted to the ventricles and the ventricular rate is controlled by the junction or the ventricles themselves. Rates with complete av block are usually 30-50 BPM but can vary. They don't usually increase unless conduction resumes. Read more...

Hi: if I have mobitz 1 av block and also SVT - does it mean my heart block can get worse because of the "underlying disease" it associated with?

Not necessarily. Both mobitz 1 second degree heart block and svt occur in structurally normal hearts. So, unless there's more to this story, you don't necessarily have "underlying disease." hence there may never be any progression. To the contrary, you might find it gets better with age. Read more...
