Do adrenal tumours cause shortness of breath with rapid heart rate?

Possibly...: They can depending upon what they are secreting.

Yes: Adrena ltumors of the medullary region, the pheohromocytomas produce adrenaline like substances that stimulate elevation in BP, shortness of breath and marked hypertensionThe diagnosis can be established by measuring catecholamines and metanephrines in plasma (blood) or through a 24-hour urine collection. Surgical resection essential after hormone production blocked.

Adrenal tumours: Rare forms of adrenal tumours can cause such symptoms,these are dangerous and need excision. All

Yes they can: Active adrenal tumors can secrete epinephrines which can cause episodes of fast heart rate with high blood pressure and flushing when you may feel short of breath. There are also adrenal tumors that are benign and don't secrete anything or cause any symptoms. There are blood and urine tests that can check if there is a problem.

Unlikely: There is a very rare adrenal tumor called a pheochromocytoma which may cause recurrent episodes of rapid heart rate and sweating but also a moderately to very elevated blood pressure. Unless you have a family history of this, it is more likely that your symptoms have another cause but if you haven't see a doctor lately and had your blood pressure checked you should do so.

Yes: some may produce a hormone that can increase your heart rate

Rapid heart rate: Any shortness of breath and rapid heart rate requires rapid attention. I would start with a visit to the nearest Emergency facility. Hope all goes well.
