Palpitations and dizziness can be concerning symptoms that may arise from various underlying conditions. It's essential to understand the potential causes and appropriate management strategies for these symptoms.

Understanding Palpitations:
Palpitations are sensations of a rapid or irregular heartbeat. They can feel like your heart is pounding, fluttering, or beating too fast. Common causes include:
1. Anxiety and Stress: Emotional stress can trigger the release of adrenaline, leading to increased heart rate and palpitations.

2. Caffeine and Stimulants: Excessive intake of caffeine, nicotine, or other stimulants can cause palpitations.

3. Medications: Certain medications, including those for asthma or high blood pressure, can lead to palpitations as a side effect.

4. Hormonal Changes: Conditions such as hyperthyroidism or hormonal fluctuations during menstruation can also cause palpitations.

5. Heart Conditions: Arrhythmias, heart valve disorders, or other cardiac issues can lead to palpitations.
In your case, you mentioned that your heart rate can reach 110 beats per minute even at rest, which is considered tachycardia. The fact that you experienced relief with Inderal (propranolol), a beta-blocker, suggests that your palpitations might be related to increased sympathetic nervous system activity or anxiety.

Understanding Dizziness:
Dizziness can manifest as a sensation of lightheadedness, unsteadiness, or a spinning sensation (vertigo). Potential causes include:
1. Vestibular Disorders: Issues with the inner ear can lead to balance problems and dizziness.

2. Low Blood Pressure: Orthostatic hypotension (a drop in blood pressure when standing) can cause dizziness.

3. Dehydration or Anemia: Both conditions can lead to insufficient blood flow to the brain, causing dizziness.

4. Neurological Issues: Conditions affecting the brain, such as migraines or transient ischemic attacks (TIAs), can cause dizziness.

5. Anxiety Disorders: Anxiety can also lead to feelings of dizziness or lightheadedness.

Given your symptoms of dizziness and the sensation of the room spinning, it is crucial to consider both cardiovascular and neurological evaluations.

Next Steps:
1. Consult a Healthcare Provider: It is essential to discuss your symptoms with a healthcare professional who can perform a thorough evaluation. This may include a physical examination, blood tests, an electrocardiogram (ECG), and possibly an echocardiogram to assess heart function.

2. Monitor Triggers: Keep a diary of when your palpitations and dizziness occur, noting any potential triggers such as stress, caffeine intake, or physical activity.

3. Medication Review: Since you experienced relief with Inderal, discuss with your doctor the possibility of resuming or adjusting your medication. However, do not stop or change your medication without consulting your healthcare provider.

4. Lifestyle Modifications: Reducing caffeine intake, managing stress through relaxation techniques, and ensuring adequate hydration can help mitigate symptoms.

5. Balance and Coordination Assessment: If dizziness persists, a referral to a specialist, such as an otolaryngologist or neurologist, may be warranted for further evaluation.

In summary, palpitations and dizziness can stem from various causes, ranging from benign to more serious conditions. A comprehensive evaluation by a healthcare professional is crucial to determine the underlying cause and appropriate treatment plan. Remember, early intervention can lead to better outcomes, so do not hesitate to seek medical advice.
